In a life without understanding of the dharma, "giving up" in an always present option. It's an easy way out which is widely practiced and accepted. We give up on friends when its too hard to keep the friendship, we give up learning things when it gets too hard and the learning becomes inconvenient, we give up on our deepest dreams after the smallest obstacle surfaces and ultimately by habit we give up our own potential.
If there is one thing we have practiced all our lives, it is to give up. Unfortunately, often dharma is not spared. Dharma is not hard but it feels difficult because it makes us confront all that is stopping us from real happiness. Dharma makes us see what is wrong with our lives and how wrong our perceptions have been about so many things. Dharma wants us to change what we have held to be the truth and let go of what we have held on so tightly.
If I am still in the Dharma it is only by the supreme kindness and the great skills of my Guru who have upheld me in courage, faith, strength and understanding, even as he has pushed me to break through all that has held me back. Without my Guru, and the love of the Dharma that he has planted so deeply into me, I would have given up.
Of all the things we may give up, dharma is one that we should never let go. When we let go of dharma we let go of the pursuit of truth, we let go of the opportunity to live a noble life, we let go of purpose in our life...and ultimately we let go of true understanding of life and what constitutes happiness.
