The Fast Track to Realization
Using your mind to circulate subtle energy through yourself can bring you to enlightenment in this lifetime. This is the fast track.
Raja Yoga and Vajrayana Buddhism both use this method.
First you receive an initiation from a teacher that tunes your energy system to a particular energy frequency. You immediately become able to do the same meditation as your teacher!
Then you do the practices that your teacher gives you. Doing your practice anchors the precious gift from your teacher in you, and it also enables you to keep deep meditation states permanently. Your entire energy system opens, clears and grows very fast.
