A. I would say Buddha-nature arises from wholehearted practice, and springs forth from commitment. When you apply yourself to wholehearted practice, practice that you are prepared to take into the whole of your life in a consistent way, then you enter the transforming process that Dharma practice promises. If you stay with your practice and continue with this same commitment, one day your true nature will open in front of you, and all the questions that you have ever asked or pondered will be answered.
