An attempt has been made in this book, to trace the origin of the Samkhya philosophy and their development which the system underwent in the different stages of its escalation and evolution. However, I have spared no pains to present the picture of early Samkhya philosophy and their general views. In this book I have discussed Samkhya Metaphysics, Dualism, Epistemology, Liberation, and God and Ethics. I have also examined theory of Gunas in the Samkhya philosophy, roughly speaking that, I have furnished comprehensive descriptions of Sattva, Rajas and Tamas. I have also discussed the relationship between Gunas and Prakrti, and the impact of Gunas in Evolution, and the Evolutes in this book. In spite of this I have discussed many more things philosophically in this very book.
