Is Yoga possible without an Energy source?

Why Yoga need an Energy space? This video is not about Sadhguru Sannidhi Sangha but about Importance of energy places for Sadhana.
I experience it very clearly when I am outside of the Ashram and inside of the Ashram. This has a huge impact on our compulsive behaviours.
It sets foundation on which Yoga can happen. it gives the basic surface where you can glide smoothly.
when it comes to experiencial aspects the effect of such spaces is tremendous. Even if a temple for that matter is muchh better place to do Sadhana or to simply sit. Try it by yourself and see, how it feels!!
