Be still like a mountain. Flow like a great river
I'd like to share another excerpt from, Inside the Yoga Sutras, by Reverend Jaganath Carrera. The following commentary is regarding living with a pure heart.
At some point in your grade-school years you were probably asked to memorize a poem to recite the next day. What did you say if you know it perfectly? "I know it by heart." Not by head, mind, or brain, but by heart. Heart implies the totality of the mind, something deeper and more stale than the usual thinking apparatus. To have a pure heart is to have a clean, steady mind--a state of nirodha. The result of this purity is that we shall see God. There is no choice implied. If your heart is pure, you will see God; no ifs, ands, or buts.
The Old Testament contains a very similar idea. It appears in Psalm 46.10. This time it is God speaking: "Be still and know that I am God." Stillness is the requirement. Stillness; no simply refraining from motion, but absolute stillness, like the calm, clear surface of a lake which can reflect like a mirror.
All those who have achieved nirodha have the gift or dual vision. They see the unity that is God behind the diversity of names and forms. They never lose sight of the Cosmic One that is the ground of all creation. How do those of us who have not attained this lofty state view the world? What happens to our perception of the Self when the mind is colored by ignorance?
