According to Osho, the moment of true knowing dissolves the 'I' and reveals three inseparable dimensions: sat—the pure am-ness of indestructible existence; chit—the realization that existence is intrinsically conscious, pervading all forms and levels; and ananda—the spontaneous bliss that arises when ego falls and conscious being knows itself. Thus knowing is simultaneously existence, consciousness, and bliss.
When real knowing happens, the ‘I’ disappears, you feel simple being, you sense that being is aware everywhere, and a natural joy shows up.
