According to Osho, the Supreme Lord has no true name; the Divine is nameless. All names - Ram, Omkar, Allah - are useful symbols, not ultimate realities. The real "Name" is the living resonance of existence: breath, heartbeat, wind, waves - love felt directly. Do not cling to words; taste the essence through love, prayer, and awareness, where every sound becomes His remembrance.
God's real name cannot be spoken; use any name as a pointer, but meet Him in love and living silence.
