If U can't forgive someone/ if U cant b happy while alone or in a group /if U differentiate human with nationality &colours or U dont share a moment to help a stranger once a day&smile then U are not yet on the track of yoga. Being a true human is yoga way, not just gymnastics!
Each bite of knowledge taking us one step ahead in the path of life. It's not going to stop us from the end; but it can reduce the pain in life what it going through. Every philosophy and science created on the base of it only. And I am pretty sure that it will remain like that till the life goes in this universe.
