Even Nietzsche Would Have Dug It

...when Trungpa puts it this way:

In bodhisattva language, the definition of friend is the idea of a guest. There is a phrase, “inviting all sentient beings as your guests.” When we invite a guest, we have a sense of the importance of the relationship. Guests are usually fed specially cooked food and receive special hospitality. The life of a bodhisattva is relating with all sentient beings as guests. He or she is inviting everyone as a guest, constantly offering a feast.
