"We have all had the experience of being so absorbed in something that we remain oblivious to things that would ordinarily distract or disturb us. Similarly, if we contemplate deeply and continuously enough upon the formless clarity of our own mind, it is possible to stop perceiving the forms, sounds, smells, and so forth that come to us through the doors of our senses. As these sensory experiences and our gross conceptual thoughts subside, the gateway to superstition closes and we become aware of an upsurge of ecstatic, blissful energy from within. This tremendous surge of bliss happens spontaneously; we do not have to fabricate it in any way. And the more we experience this deep internal state of bliss, the more profound our absorption into it will become. This opens the way for us to experience expansive, liberated, and all-encompassing states of consciousness that are presently unknown to us."

Lama Yeshe
