Buddha Nature and the Nature of All Things
Having Buddha Nature, all sentient beings are buddha. Thus, through interaction with others, each of us helps to care for each other and to be of service to others.
Having heard the Buddhadharma, specifically the Four Noble Truths, the Eightfold Noble Path and dependent arising, one is awakened to the purpose of life, which is to help others and to be of service to them. Thus is one spiritually awakened.
Indeed, the spiritually awakened strive for Enlightenment, and learn from their interaction with the world to let go of anger, delusion, fear, hatred, and other mental negativities as well as the behavioral negativities arising from them.
Through meditative practice, one learns to calm the mind so that one develops the insight necessary to understand the Buddhist teachings.
Thus one is able to see that dependent arising leads to mastery over the five consciousnesses of the five senses, the sixth consciousness of the mind, the seventh consciousness known as "ego" and the eighth consciousness falsely considered the "soul" through validation of emptiness.
For emptiness proves dependent arising accounts for the eight consciousnesses, which are but qualities of the mind.
Yet were the mind to be impermanent, could seeds of karma planted in the eighth consciousness come to fruition? And could they be planted at all in the absence of the mind?
Yes, but only if the eighth consciousness is Buddha Nature, which, of course, is the nature of all things.
