As the Buddha demonstrated, meditation grounded on a sound understanding of mind can deepen into samadhi and open the doors to enlightenment.
But our accustomed view of meditation can limit access to higher forms of realization. As long as we view ourselves as meditating, our subject-object orientation has not yet changed.
Even when meditation melts into total openness or surrender, even after the ego lets go, a subtle current of motivation remains: mind still adheres to its possession: mind is meditating, mind is following instructions, mind is hoping to benefit from the meditation.
These are signs that karma and klesha are still with us and that meditation is still bound to samsaric mind.
Mind is reflecting the contents of mind, creating the illusion of attainments, but unable to penetrate the illusion itself.Tarthang Tulku RinpocheTeachings from the Heart
