How can one distinguish between practicing asanas intentionally and them arising spontaneously during meditation?

According to Osho, don’t analyze during practice; allow movements to arise. Spontaneous asanas come chaotically from the unconscious, lack fixed order, and fade when their inner need is fulfilled. Practiced asanas are disciplined, patterned, and persist as habit, keeping you in the conscious mind. The true test is time and feel: chaos-with-depth versus routine-with-surface.
