Bodhichitta is a mind that is aimed at our own “not-yet-happening” enlightenment. We have two aspects of bodhichitta: conventional bodhichitta and deepest or ultimate bodhichitta. The difference is based on our understanding of voidness, how everything exists. Until we are a Buddha, we’re not going to be able to focus on both of these simultaneously. Nevertheless, we need to supplement relative bodhichitta with deepest bodhichitta in our practice.
