Mahāmudrā, or “Great Seal,” is a main meditative tradition in the Kagyu school of Tibetan Buddhism. Already being sealed with buddhahood, the mahāmudrā teachings emphasize relying on the ordinary mind, as it is.
Prayer for the Definite Meaning, the Mahāmudrā
Attachment to good and fixation on experiences is spontaneously liberated.
Bad thoughts and illusion are naturally purified in the element.
The ordinary mind has no rejection and adoption, no elimination and no attainment.
May we realize the truth of the true nature, free from conceptual elaborations.
The nature of beings is always buddhahood,
but not realizing that, they wander in endless samsara.
May I have overwhelming compassion
for beings in limitless, endless suffering.
When there is love with the unceasing power of overwhelming compassion,
the meaning of the empty essence appears nakedly.
May I meditate inseparably, day and night,
on the union, the supreme path, which is free from error.
-The Third Karmapa, Rangjung Dorje, in The Mind of Mahamudra, translated by Peter Alan Roberts
