Mantra Yoga... Is this for real?...

[kieranperez]

I’m about to order Om Swami’s Book “The Ancient Science of Mantras” and have been researching Mantra Yoga and this just seems almost surreal and almost like ‘come on. Astral realms, no such thing as me, everything is 1, god is everything, there is no such thing as perception, siddhis, paranormal abilities, but this???” For those who’ve researched and even done mantra yoga and Sadhana, what are your thoughts on the possibilities and claims made in this type of yoga?
