Om Vajrasattva Hum is the short form of the 100-syllable Vajrasattva mantra, one of the most important purification practices in Tibetan Buddhism and a foundational element of the Ngöndro (preliminary practices) common to all four schools of Tibetan Buddhism.
What is Om Vajrasattva Hum?
Vajrasattva (Sanskrit: "diamond being" or "vajra-minded one") is the primordial Buddha of purification in the Vajrayana tradition, depicted in white, holding a vajra (thunderbolt) and bell, and representing the inherent purity of mind that is never tainted by obscurations, no matter how thick those obscurations may appear. The short mantra "Om Vajrasattva Hum" is the essence of the longer 100-syllable mantra (the full Vajrasattva mantra), which is the most important purification mantra in the entire Tibetan Buddhist canon.
The logic of the Vajrasattva practice rests on a key Vajrayana teaching: all negative karma, broken vows, and mental obscurations are like clouds passing through an unchanging sky, they can obscure the sky of Buddha nature, but they cannot stain or damage it. Vajrasattva's practice is the method for dissolving these clouds. This understanding makes the practice not merely a moral cleansing but a recognition of the fundamental purity that was always already present.
The 100-syllable mantra is the complete form, used for intensive purification retreat practices (a standard Ngöndro requirement is 111,111 repetitions). The short six-syllable mantra "Om Vajrasattva Hum" is used for daily practice and as an accessible entry point. Both are regarded as equally potent in essence, with the longer form offering more complete coverage of all obscurations.
Word-by-Word Meaning
The short mantra contains three elements of profound significance:
- Om: the universal syllable representing awakened body, speech, and mind; the ground of all Tantric mantras
- Vajrasattva: "vajra-being"; the indestructible (vajra) being (sattva) of pure awareness; the personification of primordial purity
- Hum: the seed syllable of vajra/indestructibility; represents the indivisibility of appearance and emptiness; the "gathering" of blessings into the practitioner's mind-stream
Full translation: "Om, the indestructible being of primordial purity, Hum [let the purification be accomplished in my mind-stream]."
How to Pronounce Om Vajrasattva Hum
Phonetic guide: OM VAJ-rah-SAT-tvah HUM. "Vajra", VAJ-rah (two syllables; the "j" is soft, as in "vision," not hard as in "jump"). "Sattva", SAT-tvah (double "t"; the vowel in the first syllable is short, in the second it is an open "a"). "Hum", HUM, with a resonant nasal "m" that hums. In Tibetan pronunciation, Vajrasattva is often rendered as "Benza Satto", BEN-zah SAT-toh, reflecting the Tibetan phonetic system. Either Sanskrit or Tibetan pronunciation is accepted in practice. The mantra should be chanted clearly and resonantly, neither rushing nor dragging.
Origins and Tradition
Vajrasattva appears in the Vajrayana Tantras of Indian Buddhism, particularly the Guhyasamaja Tantra (one of the earliest and most important Tantric texts, dating to approximately the 4th–7th centuries CE) and the later Yoga Tantras. The 100-syllable mantra is found in multiple Tantric contexts and was transmitted to Tibet beginning in the 8th century with the work of the great Tantric master Padmasambhava and the scholar-translator Shantarakshita.
In the Tibetan tradition, Vajrasattva practice became the second of the four Ngöndro (foundational practices) common to all schools: Nyingma, Kagyu, Sakya, and Gelug. The requirement of 111,111 repetitions of the 100-syllable mantra in Ngöndro is one of the most demanding commitments in any spiritual tradition, often taking years to complete. The practice is understood as preparing the mind-stream for the higher Tantric practices that follow. Guru Rinpoche (Padmasambhava) is said to have proclaimed that there is no negativity too great to be purified by sincere Vajrasattva practice with the four powers of purification.
How to Use Om Vajrasattva Hum in Your Practice
The traditional Vajrasattva meditation involves visualising Vajrasattva above the crown of the head, white, luminous, seated in vajra posture, surrounded by rainbow light. As the mantra is chanted, white nectar (representing purification) flows from Vajrasattva's heart into the practitioner's crown, filling the body with light and flushing out all obscurations through the pores. This visualisation is coupled with the four powers of purification: the power of reliance (taking refuge), the power of the antidote (the mantra itself), the power of remorse (sincere acknowledgement of harmful actions), and the power of resolve (commitment not to repeat them).
For daily practice, 21 or 108 repetitions of the short mantra Om Vajrasattva Hum on a mala is accessible and powerful. More committed practitioners use the full 100-syllable mantra for their daily count. Early morning practice, before the mind is engaged with the day's concerns, is ideal. The practice closes with dissolving Vajrasattva into light that merges with one's own mind, resting in that spacious, pure awareness for several minutes.
The Benefits of Chanting Om Vajrasattva Hum
The Vajrayana tradition teaches that this mantra purifies the 84,000 negative emotions and their corresponding karmic seeds with extraordinary speed. The Guhyasamaja Tantra states that even hearing the mantra once plants liberation-seeds in the mindstream. For practitioners who have accumulated ethical lapses, broken samaya (commitments to a teacher or practice), or carry a sense of guilt or shame, Vajrasattva practice is considered the supreme remedy, not through suppression or moral condemnation, but through the recognition of inherent purity.
Psychologically, the Vajrasattva practice addresses some of the deepest layers of self-judgment and shame that block spiritual progress and undermine wellbeing. The message of the practice, that you are fundamentally pure, that no action can permanently stain your Buddha nature, is both therapeutically powerful and spiritually liberating. Regular practitioners report a lightening of psychological burden, increased emotional resilience, greater ease with imperfection, and a growing stability of mind.
