According to Osho, the “one hand clap” is the anahat nad—the unstruck, eternal sound of divine Oneness where singer and song are one. The master’s single hand is already clapping; your readiness is the missing hand. So melt, consent, and listen inwardly to Om, the ever-resounding silence beyond friction and duality.
It means there’s a quiet, always-playing sound of God inside you, heard when you relax, open up, and listen within.
