The greatest defect today is the absence of Self-Inquiry (Aathma Vichara), which is the root cause of all restlessness. If you are eager to know the truth about yourself, then you will never go astray. All pots are made of mud, all ornaments of gold, and all clothes are of yarn. Here, even though you see so much diversity, there is a unity. The basic substance of everyone is the Supreme Self (Brahman). It is your basis too!
