According to Osho, satsang is not a meeting or teaching but a living communion with truth: the dissolving of the seeker into what already is. It happens when the master's emptiness meets the disciple's emptiness, beyond words, like a fish in the ocean remembering the ocean. Stop trying to save yourself; drink, drown, and become one - tat tvam asi - the only way to know.
Satsang means being with truth so deeply and quietly that your small sense of me melts, like a fish realizing it is already in the ocean.
