In this article, I have described key aspects of the concept of causality propounded by the Buddha, Mahayana and Vajrayana Buddhism, Samkhya philosophy
, and Kashmir Saivism.
Yoga in this sense of Patanjala Yoga lends itself to any number of sectarian orientations, but most often its primary affiliation is with Samkhya philosophy, as clearly indicated in the colophons of all four sections of the Yogasutra.
The old Samkhya philosophy is, in this sense, called a tantra, namely, Sastitantra (that is, a learned system having sixty components, possibly referring to a text by that title or simply a name for the old Samkhya).
I (Cambridge, 1963), because of the system's close affinity with the Samkhya philosophy
The worldview of the Samkhya philosophy, including its ontology of the three "strands" (guna), dominates the general thinking in the Caraka-samhita, even though notions current in other philosophical schools are also used wherever convenient.
There is no doubt that the Samkhya philosophy played a major role in the medical texts; the five elements with their qualities are important notions in the medical man's view of the body and the world.
