Commentary by S Ramaswami:
“By Saṃyama on the five forms, body, perfections.
By Saṃyama on the five forms of the Bhūta mastery of them and their characteristics is obtained.
Because the body is made up of Pañca Bhūta, the Yogi can alter his own form.
So this is another Siddhi arising out of the Bhūta Jaya.
Having talked about Bhūta Jaya we now go to the Indriya Jaya or mastery of the five senses.”
