This seems to be a tentative solution, but we will find that Patanjali has landed us in a problem again. It must be noted that the greatest problem of philosophy is the problem of relation . If this cannot be explained, nothing is explained in life. Instead of solving the difficulty of explaining the relation between two things, Patanjali seems to create another problem of a need to find a relation between three things, Prakriti , Purusha and Isvara . Now, again, the problem of identity and difference arises.
Philosophy seems to have failed.
The analysis of the world leads us nowhere. The problems remain as problems, unanswered. Not a single question has been answered satisfactorily. That is where one stands, after a little bit of preliminary thought philosophically.
