When you meditation is mastered, your the mind will be unwavering like the flame of a lamp in a windless place.
In the still mind, in the depths of meditation, the Self reveals itself.
“Sati” the Self by means of the Self, an aspirant knows the joy and peace of complete fulfillment.
Sati ; Behold, Mindful, (for example; golf tee shot, tennis serve, entrance exam, your favorite hobby.)
The Bagavad Gita Chapter 6 Practice of Meditation
