Yoga has many claims with many siddhi
They are standard and written in many standard texts including Rajyoga a treatise on patanjali Yoga sutra
Are they true ? The last great person we heard of doing some of those things was Neem Karoli Baba. There were and are others but they are not in public life and do not write blogs, have no desire for disciples, giving speeches or public display like magicians.
So we must put those things aside and say we or the world is not yet ready
Then let’s go to meditation. One of the basic steps of meditation is hearing music etc. Yogananda, Aurobindo have all written about it.
My question to you is simple introspection. Have we found a real guru who can awaken that in us? Self deception of saying yes will only hurt you further – increase your vanity and deprive you of finding someone !
Can a guru do this to masses ? NO and NO
Why not ? God prevents them There are other reasons but why argue with shakti will?
