What is considered the highest form of spiritual practice for a devotee of Sai?

In Chapter 49, the text outlines a hierarchy of spiritual practices. It states that penance is greater than pilgrimages, vows, sacrifices, or charity. Furthermore, the singing of Hari's name is considered even greater than penance. However, the Satcharita unequivocally declares that the meditation on one's own Guru is the greatest of all practices. For His followers, Sai alone is the supreme object of meditation and worship. He is their secret treasure. This highlights that for a devotee, focusing one's entire being on the Guru surpasses all other religious observances and acts as the ultimate path.
