Yogasutra Vibhutipada Sutra 21-22

Sri Sadgurubhyoh Namah

21. kaya-rupa samyamat tad grahya shakti stambhe chakshuh prakasha asanprayoge antardhanam

Meaning 1: Samyama on body form can help yogi to achieve a capability of invisibility.

Meaning 2: Samyama on body form can help a yogi to actually see the body for what it is 'energy or shakti' after which the body as we are accustomed to see is no more visible.

My commentary : Yoga is practiced to change ourself, change our view, we should not be bothered about how world views us, whether visible or invisible.

The body form is also a form of energy. The entire universe is an energy pattern, while consciousness is witnessing the changing energy pattern. This energy is symbolically told as Shakti and Witness is told as Shiva.

22. sopakramam nirupakramam ca karman tad samyamat aparanta jnanam aristebhyah va

Meaning : The karma can be classified as two types depending on the fastness with which the results visit us. karma that is already set in motion (sopakramam) and dormant karma (nirupakramam). Samyama on these types of karma will tell yogi about dangers, and forewarning of death. Understanding the karma that is set in motion, will tell about how long the vehicle i.e body will run.
