How is it that man endowed with a precious and rare life, a soft heart, a sweet mind and valuable time is unable to enjoy peace? Unaware of his innate potential and forgetting his true nature, man becomes narrow minded, selfish and suffers from lack of mental peace. Ancient man led a very peaceful and happy life. Restlessness of the mind was alien to him because he adhered to Sathya and Dharma.
