"Bodhicitta or the altruistic aspiration to attain Enlightenment for the benefit of all sentient beings is a state of mind which cannot be cultivated or generated within one's mental continuum simply by praying for it to come into being in one's mind. Nor will it come into existence by simply developing the understanding of what that mind is. One must generate that mind within one's mind's continuum.
In order to engage in meditation with sustained effort over a period of time what is crucial is first of all to be convinced of the positive qualities of that mind, and the benefits and merits of generating such a state of mind. It is only when one has seen the qualities, merits and benefits of generating such a state of mind that one will be able to generate within oneself a genuine enthusiasm and perseverance in engaging in a meditation which would enable the individual to generate the mind."
-His Holiness the Dalai Lama
