There is, of course, no joy so great as the cessation of pain; in fact all joy, active or passive, is the cessation of some pain, since it must be the satisfaction of a longing, even perhaps an unconscious longing.
Those who show pity and are always ready to help during times of trouble are seldom the same ones who rejoice in our joy: when others are happy they have nothing to do, they become superfluous and lose their feeling of superiority, and so they easily show their displeasure.
Renunciation made for the sake of service is an ineffable joy of which none can deprive anyone, because that nectar springs from within and sustains life.
There is little that separates humans from other sentient beings - we all feel joy, we all deeply crave to be alive and to live freely, and we all share this planet together.
