In the Psalms of the Old Testament of the Bible it says, "Be still and know I am God."

In the Bhagavad Gita it says, "If one can see stillness in action, and action in stillness, one is the wise one among men."

For a long time, wise people around the globe have been agreeing on this one point -- Inner stillness is the essence of enlightenment.

How do we cultivate this in ourselves? -- Deep Meditation!

This is why in the AYP lessons, deep meditation is the first practice covered, as soon we establish some clarity about our desire to undertake practices. Once we are established in a twice-daily meditation routine, all the rest of the practices tend to fall into place quite naturally. A little bit of inner stillness goes a very long way toward putting us on an even keel in yoga, and in everything else we undertake in life. 

Meditation is the primary means for cultivating the inner peace and happiness that we all have been longing for. The longing is natural, for inner peace and happiness are found to be resident aspects of our inner nature when the obstructions in our nervous system begin to dissolve from the purifying influences of yoga practices.

In the AYP lessons, instructions on deep meditation begin at Lesson #13, and continue in many more lessons. See http://pathofenlightenment.org/the-wondrous-benefits-of-meditation-video-class/
