Our shastras conclude that the life of a human being is the best form among all the living beings. Shri Tulsidas ji says in Shri Ramchartimanas:

|| कबहुक करि करुणा न र देही,देत ईश बिनु हेतु सनेही ||

In Our Sanatan Paddhati describes that we get the physical body of a human being only when the Parmatma showers his mercy on us. Sanatan Dharma has been considered the oldest and the greatest dharma of the world. Scriptures of the Sanatan Dharma teaches us how to live a good life, and how can we live happily in grahastha-ashram. World's oldest scripture is 'Rigveda'. Sages and highly intellectual people of our faith have written books on each richa and mantra of Rigveda and other Vedas. Shri Krishna Dwapayan Maharishi Ved-vyasji is counted in twenty four avatars of bhagwan Shri Vishnu. Ved-vyasji has written books on Vedic philosophy including Shrimad Bhagavata Mahapurana which has been considered the best puran among all other scriptures written by other sages on Vedic philosophy.
