It is difficult to develop any good qualities or to grow from the teachings when one has pride. It originates from ignorance and reinforces a false sense of ego. Do not confuse pride with self-confidence. When our emotions are under control, when our responses to all are mild and equable, then we feel a reliable security in the teachings. This is equanimity, free of bias.
Pride is the root of bias.
A simple antidote is to think over some list or some skill you do not have. Watch another skilled practitioner of anything you can not or will not do in this life. Look at all you have and are, trace each of these to others, their skill and generosity. Finally, regard the sick, aged and dying. It is the root of all the other delusions.
