When we think about generosity, most of us probably don't think immediately of a powerful force, an inner resource, a real tool for changing how we relate to ourselves, to others and to our world. Instead we may think of it similarly to how we think of kindness or compassion - qualities that are gentle, tender, potentially self-effacing - and, as a big misconception, more aligned with weakness than strength. Largely this is because, culturally, we think of generosity purely in terms of the act of giving something up for someone else. This dynamic, by definition, implies at least some degree of self-sacrifice.
Generosity is more than just 'giving up'. Generosity generates its power from the gesture of letting go. Being able to give to others shows us our ability to let go of attachments that otherwise can limit our beliefs and our experiences. (...) This doesn't just happen passively; we choose to let (our attachments) dissolve through the cultivation of generosity. It is in that choice to dissolve that we carry ourselves to a state of greater freedom.
