Chapter 38 discusses spiritual practices for different ages. Can you elaborate on this and explain why charity is emphasized for the Kali age?

Yes, Chapter 38 provides a concise overview of the primary spiritual disciplines for each of the four cosmic ages. It states that Penance was the key practice in the Krita age, Knowledge in the Treta age, and Sacrifice in the Dvapara age. For the current era, the Kali age, the chapter identifies Charity as the most effective means for spiritual progress. Within charity, the text singles out food donation (Annadan) as the highest secret for quenching hunger and the most meritorious deed. This emphasis is rooted in the understanding that food is the sustainer of life and a direct manifestation of the Supreme Reality, making its donation a profound act of service and worship, a principle Sai Baba himself upheld.
