Pride
The more deluded your minds are, the more difficult will be your practice. Thus it is all the more important to find a wise teacher to guide you. One of the principal reasons for relying on such a teacher is in order to overcome pride.
Pride is self-destructive because it causes you to imagine that you understand something when in fact you do not.
Hence, you never ask the advice of others and just let things stay as they are. In addition, to help one heed the words of wise teachers, you need to cultivate an attitude of respect. Not only should you respect your teachers, but you need to respect yourselves.
This is achieved through seeking a true way of life for yourselves. However, if you consider the life you are leading at present to be sufficient in itself and refuse to acknowledge any other alternative, you will only give rise to further pride.
