Oṃ Āḥ Hūṃ Vajra Guru Padma Siddhi Hūṃ. (Om Ah Hum Vajra Guru Padma Siddhi Hum)
Padmasambhava was a historical teacher who is said to have finally converted Tibet to Buddhism. He was a renowned scholar, meditator, and magician, and his mantra suggests his rich and diverse nature.
Om Ah Hum have no conceptual meaning.
Om is often regarded as being the primeval sound, and in fact the sound-symbol of reality itself. It represents the universal principle of enlightenment. You can read about Om in more detail on the page about the Om Shanti mantra.
Ah, in traditional explanations, is usually said to be connected with speech (more about that in a moment) but in Sanskrit “ah” is a verb meaning “to express , signify ; to call (by name).” So it suggests evoking, or calling forth, the manifestation of enlightenment.
Hum is often thought of as representing the manifestation of enlightenment in the individual human being. This may be a complete coincidence, but hum is similar to the first person singular “aham,” which means of course “I.”
Often these syllables are associated with body, speech, and mind respectively (i.e. the whole of one’s being). So there’s a suggestion that we are saluting the qualities that Padmasambhava represents with all of our hearts (and minds, and bodies).
Vajra means thunderbolt, and represents the energy of the enlightened mind. It can also mean diamond. The implication is that the diamond/thunderbolt can cut through anything. The diamond is the indestructible object, while the thunderbolt is the unstoppable force. The vajra also stands for compassion. While it may seem odd to have such a “masculine” object representing compassion, this makes sense in esoteric Buddhism because compassion is active, and therefore aligned with this masculine symbol. (The term “masculine” does not of course imply that compassion is limited to males!)
Guru, of course, means a wise teacher. It comes from a root word, garu, which means “weighty.” So you can think of the guru as one who is a weighty teacher. Padmasambhava is so highly regarded in Tibetan Buddhism that he is often referred to as the second Buddha.
Padma means lotus, calling to mind the purity of the enlightened mind, because the lotus flower, although growing in muddy water, is completely stainless. In the same way the enlightened mind is surrounded by the greed, hatred, and delusion that is found in the world, and yet remains untouched by it. The lotus therefore represents wisdom. Again, while westerners would tend to assume that the flower represents compassion, the receptive nature of the flower gives it a “feminine” status in esoteric Buddhism, and to the lotus is aligned with the “feminine” quality of wisdom. And once again, there is no implication that wisdom is in any way limited to those who are female. The words masculine and feminine here are used in a technical sense that’s completely unrelated to biology.
And
Siddhi means accomplishment or supernatural powers, suggesting the way in which those who are enlightened can act wisely, but in ways that we can’t necessarily understand. Padmasambhava is a magical figure, and in his biography there are many miracles and tussles with supernatural beings.

俺阿吽班雜咕魯叭嘛悉地吽 Om Ah HUm VAJRa GURu PADMa SIDDHi HUM
（西藏文發音爲
Om Ah Hung Benza Guru Péma Siddhi Hung）
俺阿吽 班雜咕魯叭嘛悉地吽是蓮花生大士咒，稱爲金剛上師咒，是西藏最有名的兩種咒之壹（另壹種是大悲觀世音菩薩咒，俺嘛呢叭彌吽）
俺阿吽
有外內密三義。不過，在這三個層次上俺代表身，阿代表語，吽代表意。他們代表壹切諸佛的身語意轉化功能的加持。
就外在意義而言，俺淨化壹切身惡業（身有三惡：殺生、偷盜、邪淫），阿淨化壹切語惡業（語有四惡：妄語、惡口、绮語、兩舌），吽淨化壹切意惡業（心有三惡：貪、瞋、癡。）。 由于淨化妳的身、語、意，俺阿吽提供諸佛的身語意加持。
俺也是形色的精華，阿是聲音的精華，吽是心的精華。念這個咒，妳就是在淨化環境、妳自己和其他壹切衆生。俺淨化壹切認知，阿淨化壹切聲音，吽淨化心及其思想、情緒。
就內在意義而言，俺淨化脈，阿淨化氣，吽淨化明點。
在較深的層次裏，俺阿吽代表蓮花部諸佛的三身，俺是法身，阿彌陀佛；阿是報身，大悲觀世音菩薩；吽是化身，蓮花生大士。這個咒象征三身體現于蓮花生大士。
就秘密的意義而言，俺阿吽帶來心性三個層面的證悟：俺帶來它源源不斷的能量和慈悲的證悟，阿帶來它光輝的自性證悟，吽帶來它虛空般的明點的證悟。
班雜咕魯叭嘛
班雜比喻爲金剛鑽，它是石頭中最堅硬和最珍貴的。就像金剛鑽能切割萬物，本身卻不容易被摧毀；同理諸佛的永恒不二，絕對不會受到無明的傷害或摧毀，反而能夠斬斷壹切愚癡和業障。諸佛身、語和智慧心的聖性和作爲，有如金剛鑽般能夠穿透萬物而不受阻礙的力量，可以利益衆生。像金剛鑽壹般，沒有瑕疵；它的巨大力量來自證悟實相的法身性、阿彌陀佛的自性。
咕魯的意思是“有力的”，指具有非常殊勝德行的人，他象征智慧、知識、慈悲和方便。就好像黃金是最貴重的金屬壹般，咕魯（上師）具有不可思議、毫無瑕疵的品質、使他變成無可超越，殊勝無比。咕魯比喻報身和大悲觀世音菩薩。同時，因爲蓮花生大士教導密績之道（以“班雜”爲象征），而且透過密績的修行得到最高證悟，所以他被成爲“班雜咕魯”（金剛上師）。
叭嘛的意思是蓮花，象征蓮花部諸佛，特別是他們的覺悟話語。蓮花部是人類所屬的佛部。阿彌陀佛是蓮花部的本初佛，蓮花生大士則是阿彌陀佛的化身，因此他被成爲“叭嘛”。事實上，“蓮花生”是指他在蓮花中出生的故事。
當“班雜咕魯叭嘛”七個字母在壹起的時，也象征見、定、行的本性和加持，“班雜”義爲不變的真理、金剛鑽般、不可摧毀的本性，我們祈求在“見”中證悟它。“咕魯”代表覺悟的光明本性和神聖品質，我們祈求在我們的“定”中證悟它，“叭嘛”代表慈悲，我們祈求在我們的“行”中成就它。
因此，透過頌念這個咒，我們可以獲得蓮花生大士和壹切佛的智慧心、神聖品質和慈悲的加持。
悉地吽
悉地的意思是“真正成就”、“證得”、“加持”和“證悟”，悉地有兩種：壹般的和無上的。透過接受壹般悉地的加持，我們生命中的壹切障礙（如健康不佳）可以全部清除，我們的壹切願望可以滿足，諸如財富、地位、長壽自然會增加，生命中的各種環境也會變得吉祥，並有助于修行和覺悟。
無上悉地的成就可以産生覺悟，這是蓮花生大士的圓滿證悟境界，能利益自己和壹切衆生。因此，憶想和祈求蓮花生大士的身、口、意、聖性和作爲，可以讓我們證得壹般和無上悉地。
悉地吽可以如磁鐵吸引鐵屑般地吸進壹切悉地
吽代表諸佛的智慧心，是咒的神聖催化劑。它好像是在宣布它的力量和真理：“它就是了。”
這個咒的重要意義是：“我祈請妳，金剛上師，蓮花生大士，以妳的加持力賜給我們壹般和無上的成就。”
