What is the initial step recommended for acquiring spiritual knowledge?

According to the wisdom shared in Chapter 0, which references Lord Samarth Sadguru Dnyaneshwar Maharaj's commentary, the path to knowledge begins with service. To bring beautiful knowledge into your mind, you must "serve the saints with your entire being." This means surrendering at their feet with your body, mind, and soul, and performing all service without ego. This selfless service is described as the very doorway to the treasure of knowledge, which will enlighten the heart and ensure that doubts do not arise.
