Every day the body is moving slowly towards destruction – none can stop it. But the mind continues eternally. Body after body will come and go, but the mind will persist and take up bodies again and again until one attains complete illumination. Therefore, the main task is to make an effort to purify the mind.
(p70-71, Spiritual Treasures, Swami Turiyanandaji’s letter on 14 June, 1914 from Kankhal.)
