According to Osho, the soul neither chooses nor travels; it is pure, beginningless being—the open sky—within which bodies appear and disappear. 'Casting off' and 'assuming' belong to the transient wave of I-mind and nature’s causal play, not to the soul itself. Like clouds changing in the sky, karmic patterns reshape form, while the witnessing existence remains untouched, actionless, and uninclined.
The soul doesn’t decide to change bodies; nature and the ego’s habits do, while the soul just stays like the sky watching clouds come and go.
