According to Osho, beholding a chosen deity (Kali, Krishna, Christ, etc.) is not supreme knowledge but the final threshold before it. Here, the world’s multiplicity has collapsed into two—the devotee and God—so duality still persists. Supreme knowledge is nonduality: when both seer and seen, knower and known, dissolve, leaving only pure knowing/awareness. At that point even the deity and the devotee are ‘dropped’—the ladder discarded.
Seeing your favorite god isn’t the final truth; the real end is when both you and the god disappear, and only quiet knowing remains.
