Swami Kriyananda was a direct disciple of Paramhansa Yogananda and the founder of Ananda.
Meditation is primarily a means of helping us to know our higher or spiritual nature. It is a calm mind focused on the higher aspect of your own higher reality.
Meditation is a state of very intense awareness. Great saints and prophets of all religions felt the need to go off and pray deeply. What is prayer if you only do the talking? We need to listen for His answer. Meditation is after prayer listening for God's answer. The purpose of spiritual living is to put us in tune with higher reality.
Meditation is that stillness of mind, beyond any rights and beliefs, as the Bible says, "Be still and know that I am God." Everyone needs calmness and peace of mind.
