Samadhi
samādhiThe eighth limb, usually glossed as absorption, union, or the goal of the whole path.
The last of the eight limbs, and the hardest to say anything about. The Sutras define it as what meditation becomes when even the sense of being someone meditating drops away:
Absorption (samādhi): the deepest stage, when the sense of a separate observer thins away and only the object of attention shines.
“This same [contemplation], shining forth [in consciousness] as the intended object and nothing more, and, as it were, emptied of itself, is concentration.”
The original Sanskrit
tad evārthamātranirbhāsaṃ svarūpaśūnyam iva samādhiḥ
Notice what the definition does not promise: no visions, no powers, no escape. Just consciousness resting as the object alone, emptied of itself, as the translation puts it.
