This document discusses sadhana (spiritual practice) and seva (selfless service). It states that while seva is a form of sadhana, regular spiritual practice through sadhana is important to cultivate the selfless attitude needed for true seva. Sadhana helps remove selfish desires and vasanas (inner tendencies) to promote purity of thought, word and deed. Some examples of sadhana mentioned include reading Sai literature, listening to discourses, singing bhajans, and prayers. The document encourages joining the Sai organization to participate in collective seva efforts and help spread love, peace, and reduce fear in the world.
