According to Osho, praying for Acharya Tulsi’s “soul-peace” is meaningless: first there must be a soul, and a true soul is revealed only through meditation. Whoever has a soul is already at peace; if not, nothing can be done after death. So drop rituals for the dead and turn to meditation and conscious living that polish and unveil the soul.
You can’t calm someone’s soul after they die; if it’s truly awakened it’s already peaceful—so skip rituals and meditate to awaken your own.
