According to Osho, no. In moments of grace or bliss, time vanishes—there is neither past nor future, not even a present—only eternity. Memory needs time and mind; when grace dissolves both, recollecting past lives is impossible. In sorrow, time thickens and stretches; in happiness it contracts; in bliss it becomes zero.
When you’re truly blissful, time disappears, so you can’t remember any ‘before’ or ‘after,’ including past lives.
