How can one truly understand the Self-substance, according to the teachings in the Satcharitra?

The Satcharitra teaches that the true Self-substance is beyond the grasp of intellectual efforts like studying the Vedas, mastering philosophies, or possessing a sharp intellect. Chapter 50 explains that even the six philosophies (Shad-darshan) could not grasp it and remained only arguing. The text clarifies that this Substance is not a subject of speech or words. Instead of intellectual pursuit, the path to understanding lies in worship and devotion. By worshipping with the thought 'I exist' and investigating the non-difference between the individual soul and the Supreme Soul, the Soul becomes pleased and reveals its own nature to the seeker.
