Invocation Prayer from the Great Perfection (Dzogchen) Lineage

"Kye! To all the Buddhas of the Three Times
Inseparable from the great absolute space,
Great intrinsic nature of phenomena,
Space of awareness uncontrived and ever free,
The primordial Buddha Samantabhadra-
We bow in order to realize our self-nature,
And vow from now not to separate from it...

The primordial space of the Ground, Dharmakaya,
is the Adi Buddha among all Buddhas...
The great space beyond conceptualized views,
May we realize the nature as it is.

All-pervasiveness beyond all partiality and limitations,
Expanse free from attributes and labels,
Great confidence that there is nothing to give up and nothing to gain:
May we realize the nature as it is..."
