Light must come from inside. You cannot ask the darkness to leave; you must turn on the light.
Sogyal RinpocheThe definition of mantra is "that which protects the mind." That which protects the mind from negativity, or that which protects you from your own mind, is called mantra.
Sogyal RinpocheIn meditation take care not to impose anything on the mind, or to tax it. When you meditate there should be no effort to control, and no attempt to be peaceful. Don't be overly solemn or feel that you are taking part in some special ritual; let go even of the idea that you are meditating. Let your body remain as it is, your breath as you find it, and remain in your natural condition of unchanging pure awareness.
Sogyal RinpocheAt the beginning of meditation training thoughts will arrive one on top of another, uninterrupted, like a steep mountain waterfall. Gradually, as you perfect meditation, thoughts become like the water in a deep, narrow gorge, then a great river slowly winding its way down to the sea; finally the mind becomes like a still and placid ocean, ruffled by only the occasional ripple or wave.
