Based on Chapter 38, how does the importance of charity in the Kali age compare to the prescribed duties of previous ages?

Chapter 38 provides a clear timeline of prescribed spiritual duties across different cosmic ages. It draws upon scriptural traditions to state that Penance was the primary means in the Krita age, Knowledge in the Treta age, and Sacrifice in the Dvapara age. For the current era, the Kali age, the text identifies Charity as the principal path. As explained in Chapter 38, charity, and specifically food donation (Annadan), is hailed as the "highest secret" for this age. This highlights a shift in spiritual focus, suggesting that in the current times, the most direct path to merit and spiritual fulfillment is through selfless giving and caring for the needs of others.
