Upstairs said very well, you should cross yourself first, and then cross others. Even if you don't have to cross yourself, it is often beyond your power to help others.
Passion for animals, I think, first of all, we should not hate them. It should be understood that that is the animal's own way of life, they just fill their stomachs, they are just survival instinct, not intentional evil.
Second, be sympathetic to it. They are reincarnated in the form of animals, unable to hear the Dharma and have no wisdom to practice themselves. They have been rushing around all their lives to fill their stomachs, which is very pitiful.
Third, we should show great bodhicitta. You know, they were born in the past, or they may be people at birth, or even our former relatives and friends, but now they have become animals. We should try our best to help them and practice hard, hoping to get them over in the future and make them interested in Tao.
It's really pitiful to turn into an animal, because I can't hear Buddhism, so I can't practice and get rid of life and death. As for the method of crossing animals, I'm afraid only Buddhas and Bodhisattvas know that our wisdom is far from enough now. But I still think the landlord asked this question very well, and this kind of bodhi will certainly be of great help in the landlord's practice.
Supplementary answer: Yes, Buddhas and Bodhisattvas are all cultivated from people. Adequate leisure time is of great significance to spiritual practice. So far, there are no other examples of practicing Buddhism by Taoism. At present, all the existing buddhas are from personal practice. Therefore, Buddha has always taught us to cherish this hard-won leisure life.
You can't say that other ways are hopeless, but if you want to practice, you must first get rid of evil ways. There is no time to listen to Buddhism or even practice heterodox.
