How can i expand consciousness?
I Learnt that spirituality leads to expanding our consciousness above to our normal levels through meditation,hatha yoga etc, and every civilisation has worked out various tecniques like tantra,zen etc.Our great spiritual leaders Buddha,Jesus,Kabir,Jiddu,etc are by birth or through practice have expanded their consciousness to various levelsindividual conscious to universal consciousand various geniuses like Eienstein,Jonh Nash,Ramajunam,etc are gifted with such expanded consciousness. My question is by how we can expand consciousness techniques other than meditation and praying,satsang,yoga which i am trying noware their any scientific or logical techs to attain this, books,website or persons with fair knowledge both practical and theory help me in this regard.
