The true belief in Buddhism is not only the appearance, but also the heart, increasing wisdom. Vegetarianism is compatible with sympathy. Only vegetarianism is not Buddhism, and all cattle and sheep are vegetarians.
Eating fast is in line with heaven. It's just that fasting is not a Buddha, and Islam also fastes. But Buddha has all kinds of virtues, so I feel him consciously and feel complete. To truly believe in Buddhism, we should believe in doing things, listen to thoughts, practice, stop being smart, and correct ourselves according to Buddhism.
