All the different branches of Indian philosophy are indebted to the Samkhya system for its in-depth analysis. This is the authoritative text on Samkhya. Sanskrit Text, word by word meaning, and commentary.
We cannot see outside what we are not inside. The universe is to us what the huge engine is to the miniature engine; and indication of any error in the tiny engine leads us to imagine trouble in the huge one.
-Swami Vivekananda
