Cultivation requires patience.
Compassionate and Honest Lama Zhubo
Do not expect to let go of all anger, hatred, and attachment at once; otherwise, you will be deeply troubled by feelings of frustration, thinking that your practice is ineffective, which may gradually diminish your enthusiasm for cultivation. Cultivation requires patience; allow yourself to fail and start over. As long as you do not give up, that is enough.
