In the Nyingmapa tradition, Samantabhadra (the Buddha-Body of Reality)
is explained in accordance with the uncommon transmission of the Indestructible Nucleus
of Inner Radiance112 (Osel Dorje Nyingpo), supreme and unsurpassed among the
vehicles, that pristine cognition itself, or intrinsic awareness, is liberated right where
it is through having recognized its nature as Samantabhadra to be self-manifesting - at the
very moment when the ground arises as phenomena from the primordial ground. Samantabhadra
is the teacher in whom both samsara and nirvana are indivisible, the antecedent of all, who
holds sway over existence and quiescence in their entirety, and who is the expanse of reality
and the nucleus of the sugata. Thus Buddhahood is attained in the naturally present pristine
cognition, without thoughts of the three times, beginning, middle, and end, or of all else that
can be known.
Note 112: The Indestructible Nucleus of Inner Radiance
('od-gsal rdo-rje snying-po,
Sanskrit Prabhasvaravajragarbha) is the dimension or buddha-field of the buddha-body of reality, Samantabhadra,
which cannot be limited in space and time. The teachings of the Great Perfection [Dzogchen], which pertain to
this level, are referred to as the vehicle of the Indestructible Nucleus of Inner Radiance.
