God-realisation, or siddhi means Self-discovery in the highest sense of the term. One consciously realises his oneness with God. As long as the seeker remains in ignorance, he will feel that God is somebody else who has infinite Power, while he, the seeker, is the feeblest person on earth. But the moment he realises God, he comes to know that he and God are absolutely one in both the inner and the outer life. God-realisation means one’s identification with one’s absolute highest Self.
