Buddhism, certainly Tibetan Buddhism, places great importance on happiness. The emphasis in Mahayana Buddhism is not on one’s own happiness but rather that of all sentient beings. When we strive for the welfare of all beings, we can at the same time attain even greater happiness for ourselves. This well-being ultimately surpasses any that material enjoyment can bring. Such is the Tibetan Buddhist view on happiness.

The Buddha told us in the Vinaya that life proceeds in four separate directions: from light to light, from light to darkness, from darkness to light, and from darkness to darkness. If keeping on eating meat, one's life will be going from light to darkness. Of course, if one can avoid darkness through the practice of the Dharma, it will not be a cause for concern. But how sure are we of our practice?

The greater, more extensive compassion encompasses more than just ensuring the basic needs of sentient beings. Those needs should be taken care of, but they are not the focal point. The most important is to make all sentient beings understand the facts of samsara and the ways to be freed from it. This is the Buddha’s greatest compassion—to teach sentient beings the truth first, then the methods for liberation.

Some regard Buddhism as a kind of belief. Belief also means faith. Of course faith is needed in Buddhism, but it would be oversimplified to regard Buddhism as a belief since keeping faith is only one of many Buddhist ideas. The foundation and the priority of Buddhism are not about belief, but wisdom and compassion. Although Buddhism does advocate the importance of faith, it is not unique to Buddhism; science also calls for faith. For example, people today all want to promote faith in science. If one does not trust science, one probably would not even dare to take airplane. People take plane because they believe in the technology that allows airplane to transport people to their destination. It takes faith to accomplish anything in this world, the same kind of faith as in Buddhism. Therefore, it is incorrect to equate Buddhism with belief.

If we are given two choices:

1) we can release all the fish in the market free of charge on condition that we do not recite the Buddha’s names for them or feed them nectar pills;

2) we can recite mantras, feed them nectar pills and bless them with ‘wearing liberation’, but we cannot buy them to set them free. Which one should we choose? Make sure it is the latter.

The Buddha clearly told us that meat eaters would become carnivores such as lion, tiger, and leopard if they were to descend to the animal realm. This can be inferred through logic as well. In the animal realm, there are only two categories of food: meat or non-meat (vegetables, fruits and nuts). At that point, because of the deeply ingrained tendency to eat meat (habitual tendencies can wield great power), meat eaters will become carnivores who can only kill to survive. It is stated in the Abhidharma-kosha-shastra that there are three types of killing—killing born of greed, ignorance and anger. To kill for food is one born of greed.

Since ancient times, the one thing human beings have always longed for is happiness. Yet, with all the progress in society, what we believe to be happiness has eluded us. The rapid decline in the index on global well-being has compelled all of us to rethink: What is happiness? How do we find it? In recent years, this topic has generated even greater interest. Perhaps there are some methods in Buddhism. These methods might not work for everyone since we each have individual needs — in Buddhist terms, this is to say no one method can suit everyone since we each have karmic dispositions that are vastly different. However, for those who have the inclination, the methods can guide us in finding happiness in everyday life and at work, and in leading a fuller and more meaningful life.

Still others may wonder why the Buddha could not liberate all sentient beings with the same skillful means. The sutras said that for beings to encounter ‘liberation upon wearing’ or Bardo Thotrol (Liberation through Hearing in the Bardo), they must have had certain causes and conditions occurred in their prior lives. What does it mean by past causes and conditions? For example, one can learn Vajrayana, the Great Perfection, or listen to profound teachings such as the Tantra, Single Heir of the Doctrine in this life, but may still take rebirth in the lower realms due to improper practice or broken vows. In that case, after being in the lower realms for a very long time, one may ultimately be saved not by the exoteric practices but that of the supreme Vajrayana rather effortlessly. This is because one has previously planted the good seeds of being exposed to the Vajrayana teachings and thus accumulated the merit that eventually allows one to be liberated by the inexplicable power of hearing or wearing liberation.

The Lankavatara Sutra: If meat-eaters should be reborn in the animal realm, they would be carnivores for sure. It is because their predilection for meat in this life has left a strong habitual tendency of craving for meat in their alaya consciousness. When they take rebirth, the body may have changed, but the habitual tendencies still remain in the alaya consciousness. We can see that when this tendency is in force, some carnivores, just a few hours after being born, would hunt other small animals for food without ever being taught how to. Because they were meat-eaters in the past, the tendency to eat meat is very strong. Coupled with the fact that being animals now makes them unable to choose right from wrong, they cannot help killing for food again this time around. This is the most terrifying aspect.
