"Know Thyself. All else will be known to thee of its own accord. Discriminate between the undying, unchanging, all-pervading, infinite Atma and the ever-changing, phenomenal and perishable universe and body. Enquire, "Who am I?" Make the mind calm. Free yourself from all thoughts other than the simple thought of the Self or Atma. Dive deep into the chambers of your heart. Find out the real, infinite "I". Rest there peacefully for ever and become identical with the Supreme Self."
