Siddhas say…

That which permeates all, which nothing transcends and which, like the universal space around us, fills everything completely from within and without, that Supreme non-dual Brahman — that thou art. – Sankaracharya

That in whom reside all beings and who resides in all beings, who is the giver of grace to all, the Supreme Soul of the universe, the limitless being– I am that. – Amritbindu Upanishad

Siddhas say…

133. “As for the well-known example of the hallucination of a snake in a coil of rope the rope is real and the snake is unreal.

134-135. “Even after the true state of affairs is known and the hallucination of a snake dismissed, there is still the reality of the rope (which contains the potentiality of the recurrence of the same hallucination in the same person or in others). The danger is always there until the rope is recognised to be of and in the Self.
136. “Then objectivity totally ceases, and pure knowledge alone remains. There is thus a complete annihilation of duality.
137. “The sense of duality persists because there is the conviction of the purposefulness of the objective world. But such purposefulness and even durability is experienced even in dreams. – Tripura Rahasya
