Besides applying Udi, what other simple spiritual practices are recommended in Chapter 35 for a devotee?

Chapter 35 suggests that complex spiritual austerities may not be necessary for a devotee of Sai. Verse 221 states that simply remembering Sai, who is the embodiment of self-bliss, and chanting his name daily is a sufficient practice. This simple act of remembrance and chanting is presented as a substitute for other means like extensive chanting rituals, penance, or meditation. Furthermore, the text suggests that wherever the Sai Satcharitra is read with faith, it is as if the holy place of Dwarakamai is present and Sai himself is manifest, ready to remove any crises upon being remembered, as mentioned in verses 218-219.
