This is what the path of Dharma is like. It's not that you have to do all the practices. It is sufficient to take just one of them, whichever one you really have an affinity with, and through practicing that one alone, for the rest of your life, you will achieve enlightenment. Whichever practice you choose doesn't matter; they are all valid methods for achieving enlightenment—if you practice. The key is to practice with diligence for the rest of your life.

When we speak of the sangha, we speak of the "arya sangha," which means the "exalted sangha". At the time of the Buddha this referred to the arhats and bodhisattvas, the disciples who studied under him and achieved various levels of realization through their practice. But now who is the arya sangha? It is all of us, all of the practitioners of the present time. The moment we take refuge, which is to begin on the path, we hold the title of "sangha". As such, you should understand that you are one of the Three Jewels. You shouldn't put the Three Jewels outside of yourselves; you should always think of yourselves as being one of the Three Jewels—and that includes your body, your speech, and your mind.

To this I replied, "I still think that my body is not merely a sensory appearance, for surely it came from my parents, who were its cause and condition."
He said, "If you think that your body came from your father and mother, then what are the beginning and end of these parents? What are their source, their location, their final destination? Tell me!"
I answered, "I think that they exist, but I am not aware of what they are. It seems to me that a physical body without parents is not possible."
He retorted, "Consider this. Who are the parents of the body in a dream, in the bardo, and in the hell realms?" With that, I arrived at the decision that this body has never existed, being simply a sensory experience.
