 Tsongkhapa's explanation of the bodhisattva moral code presented in the Bodhisattva-bhūmi (Tatz 1987) follows naturally from the importance he gives to the altruistic principle (bodhicitta) in his other writing. He reconciles rules in the bodhisattva code that enjoin behavior contradicting the basic code by positing an elite that, through a noblesse oblige of the spiritually advanced, are required to do things which would be unethical in an ordinary person. Their not doing so constitutes an ethical lapse. For example, the basic code prohibits actions that influence what food a donor puts in the begging bowl (with a few exceptions for human flesh and so on), and prohibits eating after noon. The bodhisattva code contradicts the basic code insofar as it prohibits eating meat, even though, by so doing, the donor does not get the opportunity to make charity. Tsongkhapa argues that if a monk at the bodhisattva stage of development eats meat it clashes with the dictates of the altruistic principle (bodhicitta).
