Why do you think it is the next level if so next level of what?
I guess yoga is a body practice and Buddhism a way to stay poor.
Buddist find release in having nothing, a Buddha is only consciousness.
For yoga in a modern world, you need at least a mat. (joke)
Of course, you can practice on a field.
Isn't that consciousness itself is enough for life to be happy?
No, food is necessary and that leads to a conclusion that there is no next level.
Healthy food, active way of life, and mind free of addiction lead to happiness, naturally.
Of course, you can consciously deny it and show yourself how sad and brutal you can be.
There is a path of bliss and path of anger, uniting them is to be the one of Yin and Yang.
The colours of the rainbow so pretty in the sky... do or die.
Life is Love expressed in infinite ways.
Love is oneness and one is all.
Ego cogito, ego erro, cor sict. - I think, I mistake, soul knows.
If I am that which is nothing that exist but receives existence, what can happen to me, even if there will be no existence - that will be my purity.
