According to Osho, Sangham Sharanam Gachchhami means surrendering to the living commune of the awakened one—the sangha—not as an organization but as a universal fellowship of disciples wherever they breathe. Harder than surrendering to a master, it asks you to bow to ordinary seekers, deepening love, dissolving ego, and preventing the subtle pride of being a 'great disciple' by surrendering, in humility, to millions.
It means trusting and learning from the whole loving community of fellow seekers everywhere, not just the master, so your ego softens.
