Elimination of drisya (objects) means elimination of separate identities of the subject and object.

Devotee:  Why should the objects - drisya be eliminated? Cannot the Truth be realised even keeping the object as it is?

Ramana Maharishi:  No. Elimination of drisya means elimination of separate identities of the subject and object. The object is unreal. All drisya (including ego) is the object. Eliminating the unreal, the Reality survives. When a rope is mistaken for a snake, it is enough to remove the erroneous perception of the snake for the truth to be revealed. Without such elimination the truth will not dawn.
