Buddhism believes the nature of happiness is neither a steady income nor harmony in the family, neither the joy of seeing the world nor a glass of water. Although all may bring a sense of well-being, they are not the nature of happiness.

The Buddha instructed us to follow the middle way, to avoid extreme measures in any situation. We need not be resentful, disgusted, or pessimistic in life; but we should not see life as perfect either. Wealth and relationships are neither good nor bad on their own; whether they become good or bad depend on the mind. If we look upon wealth, relationships, and other worldly pursuits with equanimity, our life will be that much happier.

Still some others who do practice but only for the hope of gaining health, wealth, and other benefit through the blessings of the Buddhas and bodhisattvas. Of course, absent any adverse conditions, praying to the Buddhas and bodhisattvas can help us reach our goals. But the short-term goal of obtaining worldly fortunes should never be the choice of a dharma practitioner.

Of course, it has never been easy for worldly people to just let go, but it may not be that difficult if one can adopt the Buddhist way to handle it. Many people choose the extreme method to end their suffering because they don’t know any other way. However, letting go is not so hard if one knows how to do it. When a relationship comes to an end, just let it end naturally, like all other conditioned phenomena. The important thing is to control one’s desire or attachment and face the change rationally. To be able to keep desire, aversion and delusion under control is not only very helpful in real life but can also guide us to liberation.

Desire also means greed which can be defined in a broad or narrow sense. Broadly speaking, it encompasses desire for money, fame, love and even liberation; while in a narrow sense, it only points to desire for money, fame, status and the likes. Desire needs be properly managed lest it should cost us much suffering, especially when directed toward a person of one’s desire, the suffering can be even more damaging. For example, if a husband or a wife has an extramarital affair, his or her other half will usually suffer a tremendous blow mentally as it is most difficult to accept the fact and let go. The ensuing effect ranges from experiencing depression to taking one’s own life. In such case, it is even more crucial to control the desire to grasp—what is the point of hanging on to a person who no longer feels enamored with you? Therefore, the Buddha said 2500 years ago that breaking up other people’s family is a very serious misdeed, with sexual misconduct being one of the ten non-virtues. Although marital problems were not as notable or serious then, they have become a very common and critical social issue today.

What is the difference between Mahayana and Hinayana Buddhism? It is a matter of having bodhicitta or not.  

What is bodhicitta? The answer is simple and known to everyone, at least in words: bodhicitta is the wish to attain Buddhahood so as to be able to liberate all sentient beings. But in practice, it is not so easy at all. Even some senior monks and people who claim to be yogis of the Great Perfection school or Vajrayana practitioners have yet developed genuine renunciation and bodhicitta.

On the other hand, many people feel insecure without money or the care of their children in old age, so they busy themselves all the time with the task of making money. As a result, their older years might have been well provided for, but not at all for their future lives. Eventually, everyone has to go through death and rebirth. It is startling to see that people in the secular world make no preparation for either.

In whatever work or research we engage in, we must begin by understanding its basic nature. Thus, let us first establish — what is happiness? What is the nature of happiness? A Chinese book titled “What is Happiness” addresses this question from the viewpoint of 155 experts from around the world. For instance, happiness is having a stable income; happiness is harmony in the family; happiness is travelling around the world; happiness is just a glass of water, etc. There is no consensus.

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.
