Yoga is nothing but an effort into “Bhoot Shuddhi” (or Purification/Balance of over the 5 elements). Whatever is done in yoga is towards that. Once we have done the necessary Sadhana towards Bhoot Shuddhi, we get what is called as “Bhoot Siddhi” (Control over the 5 elements). At that time, you can do whatever you want you have such mastery.
Sadhguru talks about the nature of elements and Water in specific.
