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.

Normally, when we are free from any physical suffering and encounter no difficulty in our daily life, we think the world is so good that we do not feel necessary to be mentally or physically prepared for impermanence. Just relax and idle the time away. Should some misfortune befall us, we would likely be caught off guard and much distracted as to what to do. By then it may be too late to even turn to the Buddha as a last resort.

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.

We never believe, however, that this world is arising and ceasing momentarily but assume time runs through the past and future. We always consider that getting off work and going home are two different things. We never think that the only time we have is one ten thousandth of a second, and neither do we believe that this world is only one ten thousandth of a second. The reason we are not able to observe this with our naked eyes is because the arising and ceasing of objects is extremely fast.

We also cannot gather the past, present and future into the same time and the same place. If the past, present and future of that happened, our concept of time would be mistaken. Then, yesterday, today and tomorrow can also be gathered into the same time and same place.  If such happens, our concept of time again would be mistaken. Therefore，we live in a dream-like world.

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.

Naturally, we cannot hope to give up all desires right from the outset, which is impractical and also unnecessary. Mahayana Buddhism is a system of ideas very much in tune with human nature. It does not demand all practitioners to become ascetics; rather, it advocates a middle way approach in the way of living, meaning not overly extreme. For example, due to a mistaken belief that hardship can lead to liberation, one deliberately endures hunger and wears shabby clothing when in fact one can easily afford a comfortable life. Rather than being helpful, such behavior may even become an obstacle to one’s practice sometimes. Conversely, choosing to live extravagantly and be unappreciative of anything in hand is another extreme. The right way, that is, the middle way, is to keep our desire properly under control.

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.
