Upanayana () is a Hindu educational sacrament, one of the traditional saṃskāras or rites of passage that marked the acceptance of a student by a preceptor, such as a guru or acharya, and an individual's initiation into a school in Hinduism. Some traditions consider the ceremony as a spiritual rebirth for the child or future dvija, twice born. It signifies the acquisition of the knowledge of and the start of a new and disciplined life as a brahmāchārya. The Upanayanam ceremony is arguably the most important rite for Brāhmaṇa, Kṣatriya, and Vaiśya males, ensuring their rights with responsibilities and signifying their advent into adulthood.

The tradition is widely discussed in ancient Samskṛta texts of Hinduism and varies regionally. The sacred thread or yajñopavīta (also referred to as Janeu, Jandhyam, Pūṇūl, Muñja, and Janivara Yonya) has become one of the most important identifiers of the Upanayana ceremony in contemporary times, however this was not always the case. Typically, this ceremony should be performed before the advent of adulthood.

Etymology According to the given community and its regional language, it is also known by numerous terms such as:

upanayanam in Saṃskṛtam (उपनयनम्) mekhal in Kashmiri (मेखल/میکھَل) janeo in Punjabi (ਜਨੇਓ) upnen/upvit in Rajasthani (उपनेन/उपवीत) jānoi in Gujarati (જાનોઇ) janya in Sindhi (जन्य) janev in Bhojpuri (जनेव) upnæn in Maithili (উপনৈন) munja in Marathi (मुंज) munji in Konkani (मुंजी) poite in Bangla (পৈতে) brataghara/baṛughara in Odia (ବ୍ରତଘର/ବଡ଼ୁଘର) logun dioni in Assamese (লগুণ দিওনী) bratabandha in Nepali (ब्रतबन्ध) chhewar in Newari (छेवार) upanayana in Kannada (ಉಪನಯನ) upanayanamu/odugu in Telugu (ఉపనయనము/ఒడుగు) upanayanam in Malayalam (ഉപനയനം) upanayanam or pūṇūl in Tamil (உபநயனம் or பூணூல்).

Upanayana Upanayana literally means "the act of leading to or near, bringing", "introduction (into any science)" or "initiation" (as elucidated by Monier-Williams). Upanayana is formed from the root √nī meaning 'to lead'. Nayana is a noun formed from the root √nī meaning 'leading to'. The prefix upa means 'near'. With the prefix the full literal meaning becomes 'leading near (to)'. The initiation or rite of passage ceremony in which the sacred thread is given symbolizes the child drawn towards a school, towards education, by the guru or teacher.Monier-Williams (1899) "upanayana" in Monier-Williams Sanskrit-English Dictionary, 1899. Via Cologne Digital Sanskrit Dictionaries. At Institute of Indology and Tamil Studies, University of Cologne, Germany. pp. 201 (print edition). The student was being taken to the Gods and a disciplined life. As explained by PV Kane, taking (the child) near the acarya (for instruction), or alternately "introducing to studenthood". It is a ceremony in which a teacher accepts and draws a child towards knowledge and initiates the second birth that is of the young mind and spirit.

Variations A popular variation is Mauñjibandhana, derived from two words muñja, a type of grass, and bandhana which means to tie or bind. The munja grass is tied around the waist. This word was used by Manu. Another variation is vratabandha(na) meaning "binding to an observance". The word janeu is a condensed version of yagyopaveeta. The ceremony is also known as punal kalyanam (meaning auspicious thread ceremony) and Brahmopadeśa.

Yajnopavita The sacred thread or upper garment is called the yajñopavīta (), used as an adjective, which is derived from the terms yajña (sacrifice) and upavīta (worn). The literal meaning would then become "something worn on the body for the sacrifice". Accoutrements offered along with the yajnopavita may include be a daṇḍa (staff) and a mekhala (girdle).

Description

Background The earliest form of this saṁskāra, of whose names there are no record, may have been to mark the acceptance of a person into a particular community. Indologically, the ritual is present in the Gṛhyasūtras and Dharmasūtras and Dharmaśāstras, as well as a couple of times in the Saṃhitās.

Educational courses or training has been referred to in the Chandogya Upaniṣad and in the Yājñavalkya Smṛti; Gharpure writes that during the Smṛti period, Upanayana may have attained a permanent fixture if the life of students to be as compared to being optional before.

In the Atharvaveda, and later in the Sutras period, the word upanayana meant taking responsibility of a student, the beginning of an education, a student's initiation into "studentship" and the acceptance of the student by the teacher. Preceptors could include a guru, ācharya, upādhyāya, and ṛtvik.

Gradually, new layers of meaning emerged, such as the inclusion of goddess Sarasvatī or Sāvitrī, with the teacher becoming the enabler of the connection between this goddess and the student. The meaning was extended to include Vedāngas and vows among other things.

The education of a student was not limited to ritual and philosophical speculations found in the Vedas and the Upaniṣads. It extended to many arts and crafts, which had their own, similar rites of passages. The Aitareya Brāhmaṇa, Āgamas, and Purāṇas genres of literature in Hinduism describe these as Śilpa Śāstras. They extend to all practical aspects of culture, such as the sculptor, the potter, the perfumer, the wheelwright, the painter, the weaver, the architect, the dancer, and the musician. The training of these began from childhood and included studies about dharma, culture, reading, writing, mathematics, geometry, colours, tools, as well as traditions and trade secrets. The rites of passage during apprentice education varied in the respective guilds. Suśruta and Charaka developed the initiation ceremony for students of Āyurveda. The Upanayana rite of passage was also important to the teacher, as the student would therefrom begin to live in the gurukula (school).

Upanayana became an elaborate ceremony, that includes rituals involving the family, the child and the teacher. A boy receives during this ceremony a sacred thread called the yajnopavita to be worn. The yajnopavita ceremony announces that the child had entered into formal education. In the modern era, the Upanayana rite of passage is open to anyone at any age. The Upanayana follows the Vidyārambhaṃ, the previous rite of passage. Vidyārambhaṃ became an intermediary samskāra following the evolution in writing and language. Vidyārambhaṃ now marked the beginning of primary education or literacy while Upanayana went on to refer to spiritual education. The Upanayana can also take place at the student's home for those who are home-schooled. Ceremonial bhikṣa as one of the rituals during Upanayana became important, attaining sizeable proportions. The actual initiation occurred during the recitation of the Gāyatrī Mantra. The spiritual birth would take place four days after the initial Upanayana rituals. It was then that the last ritual was performed, the Medhajanana. The Samavartanam or convocation ritual marked the end of the course. The Upanayana became a permanent feature around the Upaniṣad period.

Attire includes a daṇḍa or staff and a mekhala or girdle.

Age and varna

In Hindu traditions, a human being is born at least twice—once at physical birth and second at intellectual birth through teacher's care. The first is marked through the Jatakarman rite of passage; the second is marked through Upanayanam or Vidyārambha rites of passage.Mary McGee (2007), Samskara, in The Hindu World (Editors: Mittal and Thursby), Routledge, , pages 332–356 A sacred thread was given by the teacher during the initiation to school ceremony and was a symbolic reminder to the student of his purpose at school as well as a social marker of the student as someone who was born a second time (dvija, twice born).Raman Varadara, Glimpses of Indian Heritage, p. 51, .

Many medieval era texts discuss Upanayana in the context of three of the four varnas (caste, class)—Brāhmaṇas, Kṣatriyas and Vaiśyas. The ceremony was typically performed at age eight among the Brāhmaṇas, at age 11 among the Kṣatriyas, and age 12 among Vaiśyas. Apastamba Gryha Sutra (verse 1.1.1.27) places a maximum age limit of 24 for the Upanayana ceremony and start of formal education. However, Gautama Gṛyha Sūtra and other ancient texts state that there is no age restriction and anyone of any age can undertake Upanayanam when they initiate their formal studies of the Vedas.

Śūdras, or the fourth varna, do not have the rite to the Vedic Upanayana or access to Vedas as their vidhi is not mentioned in any of the Dharmashastras.Hartmut Scharfe (2007), Handbook of Oriental Studies, Brill Academic, pp. 102–103, 197–198, 263–276, .

The large variation in age and changes to it over time was to accommodate for the diversity in society and between families.

Vedic period texts such as the Baudhāyana Gṛhyasūtra encouraged the three Varṇas of society to undergo the Upanayana.

Initiation to sectarian affiliation is not exclusive to ascetics, but open to householders.

Gender and women In some texts, some girls belonging to the three varnas undergo upanayana rite of passage. In ancient and medieval eras, texts such as Harita Dharmasūtras, Aśvālayana Gṛhya Sutra and Yama Smriti suggest women could begin Vedic studies after Upanayana.V.L. Manjul (December 2002). "Starting Vedic Studies—Backed by scripture, girls get their sacred thread"; Archived on 15 January 2021. Hinduism Today.C, Tripathi (2005). The Evolution of Ideals of Womenhood in Indian Society. p. 94. .

Girls belonging to the three upper varnas who decided to become a student underwent the Upanayana rite of passage, at the age of 8, and thereafter were called Brahmavadinī. They wore a thread or upper garment over their left shoulder. Those girls who chose not to go to a gurukula were called Sadyovadhu (literally, one who marries straight). However, the Sadyovadhu, too, underwent a step during the wedding rituals, where she would complete Upanayana, and thereafter wear her upper garment (saree) over her left shoulder. This interim symbolic Upanayana rite of passage for a girl, before her wedding, is described in multiple texts such as the Gobhila Gṛhya Sūtra (verse 2.1.19) and some Dharmasutras.

Yajnopavita

The sacred thread or the yajnopavita has become one of the most important parts of contemporary Upanayana ceremonies. There are accordingly a number of rules related to it. The thread is composed of three cotton strands of nine strands each. The strands symbolise different things in their regions. For example, among Tamils, each strand is for each of the Tridevī, the supreme trinity of the Hindu goddesses Sarasvatī, Lakṣmī, and Pārvatī. According to another tradition, each of the nine threads represents a male deity, such as Agni, Bhaga, and Chandra.

The predecessor to the sacred thread was an upper garment (such as a dupatta or an uparane). However, as traditions developed, the upper garment began to be worn continuously. The usage of a thread grew out of convenience and manageability, becoming more popular than alternatives such as a kusa rope.

The ancient Saṁskṛta texts offer a diverse view while describing the yajñopavītam or upavita. The term upavita was originally meant to be any upper garment, as stated in Apastamba Dharmasūtra (verse 2.2.4.22–2.2.4.23) or, if the wearer does not want to wear a top, a thread would suffice. The ancient Indian scholar Haradatta states, "yajñopavītam means a particular mode of wearing the upper garment, and it is not necessary to have the yajñopavīta at all times".
