I see "Om ah hung vajra guru pema siddhi hung" but also "Om ah hum vajra guru padma siddhi hum".

I know the first is Sanskrit mixed with Tibetan and the latter is pure Sanskrit. I also am aware that it is about how the Tibetans pronounce Sanskrit.

Is one preferred or more authentic? Is it up to the individual?

Any elucidation on this matter is greatly appreciated. Thank you.

First, the spelling of the mantra in Devanagari ("Sanskrit") and Tibetan scripts:

Devanagari Vajra Guru Mantra

Transliteration: oṃ āḥ hūṃ vajra-guru padma-siddhi hūṃ

Tibetan Vajra Guru Mantra

Transliteration: oṃ āḥ hūṃ badzra-guru padma-siddhi hūṃ

The following two characters differ (Tibetan script followed by IPA): བ = /ba/, ཛ = /dza/. Why is that? There's no व "va" in the native Tibetan alphabet, so the options are ཝ "wa" or བ "ba". In this case, "ba" has been chosen. Letter ཛ /dza/, instead of the native "ja" ཇ /dʒa/, is commonly used to transliterate the Devanagari ज "ja", being phonetically closer (although not identical). The spelling of "padma" is identical, however in Tibetan the pronunciation becomes "pema". Likewise "badzra" becomes "benza", non-native Sanskrit conjuncts like "dzr" often morph like that. The literal spelling "pema" has also entered some Tibetan texts, though I haven't seen it used for this particular transliteration.

There are also variations (regional/lineage/historical) of the actual pronunciation in Tibetan, so the answer to your question, "which version is more authentic", depends largely on "according to whom". Undoubtedly each Tibetan lineage will hold that their version is the preferred one. If you should find an Indian Vajrayana practitioner from a native lineage, they would probably prefer the Sanskritic version. If you happened to find a heir to the Mahasiddhas of early medieval Bengal, chances are they'd prefer you muttering "bojro-guru podmo-siddhi" instead. To each their own, I say, and all success.

"Is it up to the individual?" Again, it depends. If you follow a traditional Lama who has inherited a certain version, then that's probably what you are expected to emulate. (Be aware that Roman transliterations in Tibetan writings available in English are often approximate, if not crude, and non-standardized. Find a recording and follow that if you want to have it 100% per the source.) If you follow your own lead, then yes, surely it is up to you, and your experience, which variant you may prefer.

If you're a lonely rider on the path to nowhere, you will want to burrow into the effects of each version and try to pin down the mind-space and energy impact conjured by each variant, along with the syllables when individually uttered. (This is worthy practice with any mantra and in any case.)

The greatest benefit follows from no particular pronunciation, but from the skill of entering the mantra and deploying it as a medium for entering the "lotus-born diamond-master" space of awareness, flanked by the energies of the seed-syllables — and in due course embodying all that yourself.

The pure Sanskrit is the best from my subjective experience. Remember Padmasambhava was Indian and although he was an Indian Buddhist, he came from the Brahmin caste, was a sadhu , and he carries Rudra / Shiva's Trishula ( Trident ) and an Aghori skull cap. Both very powerful symbols of Himalayan Shaivism. There is something very unique about Padmasambhava , for my intuition tells me his Ishta Dev was Rudra.


Alexander is correct on the Tibetan and you are close on the other Sanskrit version, but the words are out of order. OM AH HUNG VAJRA GURU PEMA SIDDHI HUNG is the order of the one you refer to in your question. However, both are actually Sanskrit. It is just a different arrangement of essentially the same words. Both are equally correct, just from different cultural aspects.


The Sanskirt version is best one to practice. The other ones sound too nasally and the feeling in my body when I practice different.

"Ohm a hum vajra guru padma siddhi hum" x3

That being said, it is a mantra referring to a Tibetan saint/reincarnation of Gautama... so maybe the Tibetan pronunciation would be more powerful.. I haven't practiced that one long enough to know.
