Tenzin Gyatso, the Fourteenth Dalai Lama
"What do we mean by bodhisattva? Bodhi means enlightenment, the state devoid of all defects and endowed with all good qualities. Sattva refers to someone who has courage and confidence and who strives to attain enlightenment for the sake of all beings. Those who have this spontaneous, sincere wish to attain enlightenment for the ultimate benefit of all beings are called bodhisattvas. Through wisdom, they direct their minds to enlightenment, and through their compassion, they have concern for beings. This wish for perfect enlightenment for the sake of others is what we call bodhichitta, and it is the starting point on the path. By becoming aware of what enlightenment is, one understands not only that there is a goal to accomplish but also that it is possible to do so. Driven by the desire to help beings, one thinks, For their sake, I must attain enlightenment!"
