Samaya

Samaya (समय) — the tantric vow or commitment — is the set of binding obligations that a practitioner assumes upon receiving initiation (dīkṣā) into a tantric tradition. It defines the relationship between guru and disciple, establishes the ethical and ritual framework for practice, and governs the conduct of the practitioner within the mandala community. In both Hindu and Buddhist Tantra, samaya is the glue that holds the tantric lineage together and ensures the continuity of the transmission.

In Buddhist Tantra (Vajrayāna), the samaya vows are extraordinarily detailed and carry severe consequences for their breach. The Hevajratantra and Guhyasamājatantra enumerate specific commitments: maintaining devotion to the vajra master, protecting the secrecy of practices, not sharing tantric teachings with the uninitiated, and maintaining the integrity of the three vajras (body, speech, mind of the Buddha). Keown’s dictionary (as cited in the Wikipedia article) defines samaya as: a particular system of teaching or doctrines; the conduct required of a tantric practitioner, often as a set of vows; the realization (abhisamaya) of Buddhahood; and union with the trikāya.

In Hindu Śākta and Śaiva Tantra, samaya similarly governs the practitioner’s relationship to the guru and the tradition. The Kularṇavatantra and Vāmakeśvaratantra outline the behavioral codes expected of initiates, including dietary restrictions, ritual obligations, and ethical conduct. The concept of samaya in the Kaula tradition takes on an additional dimension: the practitioner’s commitment to seeing all experience as sacred, all beings as manifestations of the divine, and all action as worship. Violation of samaya is believed to bring spiritual ruin not only to the individual but to the entire lineage.

Verification notes

• The Hevajratantra and Guhyasamājatantra are the primary sources for Buddhist tantric samaya.
• The Kularṇavatantra provides a Hindu Śākta treatment of initiatory commitments; the uncertain edition attribution was removed.
• The claimed samaya classification in Abhayākaragupta’s Abhisamayamañjarī (a Prajñāpāramitā gloss) and Niṣpannayogāvalī (a mandala compendium) was removed; Keown’s fourfold definition from the ref extract was added.
• Per the Wikipedia ref, samaya is treated primarily as a Vajrayāna concept; the Hindu usage is a related but broader sense.
