The morning bell chant comes from the Avatamsaka Sutra. This sutra talks about the interdependence of all beings. So all animals, birds, human beings, demons, and beings in hell hear the sound of the bell, wake up, get enlightenment, and become Buddha. Together, we all become Buddha. So at the time when you just hear the sound of the bell, universal nature appears, name and form disappear, and everything becomes equal.
Great love is substance, and great sadness is compassion.
If other people are suffering, I am sad and compassionate. If everyone is happy, I am happy. The Great Dharani, which we chant, is a long mantra and has no translation. In Buddha's lifetime, one monk broke the precepts and was very unhappy. If you hold your mistake, your karma will never go away.
