The aims in life vary among individuals. To know the purpose of life, a person needs to understand the nature of a man and when the person understands it, then some important realizations arise. Based on the relisations and understanding, he will be more aware of his speech, thoughts and actions. Throughout the cultivation of positive qualities, his wisdom, love, compassion, kindness and joy grows. With that, he has a greater awareness to all forms of life and better understanding of his own thoughts, feelings and motivations. He will strive to eradicate greed (which I believe greediness exists in every human being), develop wisdom and compassion, and to be liberated frm the bounds of sufferings.
