According to Osho, Shiva and Saraha differ only in form, not in essence. Shiva’s Tantra moves through devotion, prayer, and the heart; Saraha’s through meditation, awareness, and the mind. Both dissolve the ego: Shiva as lover and beloved merging, Saraha as two zeros—shoonya—disappearing. The destination—enlightenment—is identical; choose the path matching your temperament: feeling (love) or thinking (intelligence).
One path loves totally, the other watches thoughts totally; either way the little ‘me’ disappears into the same peace, so pick what suits your heart or your head.
