The true faith in Buddha is not only in the appearance, more important in the heart, in the increase of wisdom. It is a very good idea to have a vegetarian diet, and it is a good idea to be compassionate. The only thing that is not a Buddha is a vegetarian diet; all cows and sheep are vegetarians.
Fasting is the way of heaven. Lent alone is not Buddha, Islam also eats fasting. But the Buddha has all the virtues, self-awareness, self-realization, self-actualization. True faith in Buddha consists of faith, wishing, hearing, thinking and practicing, cessation, meditation and wisdom, and correcting oneself according to the teachings of the Buddha in accordance with reason and law.
