As a devotee with a restless mind seeking purity, what does this scripture suggest is the most effective approach?

For steadying a restless mind and achieving inner purity, the scripture strongly advocates for the company and grace of the Guru. Chapter 1 explains that nothing is as restless as the mind, but the Sadguru can make it steady at the feet of Hari. His company is compared to the purifying water of the Ganges, which washes away impurities and makes one pure. Furthermore, the text highlights that the "mantra of the Guru" and his holy name contain vast power. By engaging in these practices and dedicating oneself to the Guru's service, a devotee can find stability and be unknowingly guided toward the ultimate goal of liberation.
