According to Osho, to cultivate the feeling of dying at night means letting the constructed 'I' dissolve into zero so only the silent witness remains. Do not affirm 'I am the witness'; instead, relax the sense of me, watch thoughts and identity fade, and surrender as if dying. In that egoless absence, the ever‑present consciousness reveals itself.
Before sleep, imagine your ‘me’ melting away and just keep quietly watching until only the watching is left.
