Does one need to perform specific rituals to be a devotee of Sai, or is simple remembrance sufficient?

The provided text suggests that both paths are valid and powerful. The author personally emphasizes a path of constant remembrance, stating, "I have no other chanting (Japa), no other penance (Tapa); I behold only one form with qualities—the pure form of Sai." This highlights that sincere, focused devotion and thinking of Sai day and night can destroy the fear of worldly existence, as mentioned in Chapter 1. On the other hand, Chapter 1 also describes the path of 'Archan' (worship) as a valid form of devotion. This path involves expressing love through specific actions and rituals, such as bathing an idol and offering food (Naivedya), all done with love. The key seems to be the underlying emotion of love and faith, whether expressed through internal remembrance or external rituals.
