What are the spiritual benefits and processes described in Chapter 46 that result from surrendering to the Guru and chanting his name?

As detailed in Chapter 46, surrendering body, speech, and mind at the Guru's feet and constantly chanting his name is a powerful practice for spiritual purification. This devotion washes away sins and diminishes the qualities of 'Rajas' (passion) and 'Tamas' (ignorance). Consequently, the quality of 'Sattva' (purity) gradually increases, leading to the accumulation of Dharma. This righteous disposition then naturally brings about detachment from worldly subjects, paving the way for the instant manifestation of self-knowledge and a state of peace.
