Yoga Sutra 4.01 Perfections siddhi arise

Perfections (siddhi) arise from birth or from drugs or from mantra-s or from tapas or from samādhi

The perfections from birth are in a different body, being attainment of another body in heaven or some similar region, by yoga or by other means. From drugs – such as an elixir of the demon realms: here the original body is not discarded, but by taking drugs like soma or the amalaka plant (some perfection is attained), by mantra-s being murmured are attained levitation, etc.; by tapas (are attained) such abilities as taking on any form and going anywhere at will. The perfections from samādhi have been described as already set out (in the Third Part).

The perfection which is from a specific cause is superior to the others. It is true of course that in the case of perfection of birth, the new body will have been supplied from the fact that a causal condition was set up in the past. But as regards that change into another birth, with a body that has not yet come into being, is that specific causal condition alone the material cause of it, or is there indeed something else?
