To transform our negative emotions, first we must understand the base, which is ourselves in this life. Then, we have to understand dependent arising, or emptiness, which is revealed through existence. When you see the truth and understand the true nature of reality, result will be to no longer create any karma to continue in this creation of life. Attachment is the glue to samsara. When contaminated attachment to the six senses stops then an opening comes for uncontaminated six senses, and true joy can arise. The beginning of this effort is the most difficult, but once you get used to applying antidotes to negativities it begins to become effortless. But we have the habit of laziness. Enthusiasm is the direct opponent to laziness, all three types.
