Kama (desire) Krodha (anger) Dwamsin (who destroys). In the Vishnu Sahasranama, too we have the epithets, Kamahaa, and Krodhahaa, meaning, one who destroys Kama and one who destroys Krodha. Krodha or resentment comes when Kama or desire is opposed, foiled or not fully realized. Desire (kama) for worldly things can never be satisfied or satiated; one desire leads to another.
So, Baba says, speaking of the Purusharthas (the four goals of man) Dharma, Artha, Kama and Mokhsa; 'Acquire Artha (Wealth) through Dharma (Morality); develop Kama (desire) for Moksha (liberation from the ignorance of Reality).'
It is thus that Baba destroys Kama and its consequence Krodha. Once you start seeking Liberation through Japa and Dhyana, His Grace leads you on, step by step, steadily and securely, until you merge in the Sea of Bliss.
When you discover that all is Sai, all is the same Sai that is in you, whom can you hate? When we realize that it is Sai who gives us whatever is best for us, what else can we desire and what else can we strive for, except His grace? The very nature of a Sai devotee is transformed by His Grace into a Santha (quiet, calm, undisturbed) Swarupa (embodiment). Where Grace and Love prevail there can be no room for desire and anger. Santhi is achieved through desirelessness, and Prema is won through victory over anger.
