I've been able to give up views when I've recognized that I didn't need them to protect my sense of self. In fact, they are easier to give up when I see that attachment to views constructs a sense of separate self and adds to my suffering. I think another manifestation of generosity is giving up destructive habits or lingering grudges. In moments of clear seeing, which come through practice and perhaps by grace, we understand that anything we hold on to, whether material or emotional, is a potential source of complication and of suffering. With that understanding, generosity becomes easy.
Morality is the second of the paramis.
The commentarial tradition says morality has a composing effect. The practice of morality steadies and balances the mind and allows it to see clearly. Seeing clearly, we know that there's a tremendous amount of inevitable pain that is part of life experience, and the impulse to respond with impeccable morality, to not add further pain to the inevitable discomfort of life, becomes spontaneous. The parami of renunciation is often thought of as giving up something tangible in life. In Buddhist scripture it is usually to describe renouncing the world and joining the Order of monks and nuns.
