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 the aspects of Buddhism.  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 planes because they believe in the technology that allows airplane to transport people to their destinations.  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.

To Give Is to Receive

Perhaps someone might ask how we can solve our own problems if we only help others.

Actually, there is a hidden secret here which only someone like Buddha Sakyamuni can know. That is -- when we let go of our attachment to the self and think only of benefiting others, we inadvertently receive all the things we deserve.

To give an example, when people rushed to help raise funds for victims of a natural disaster, some beggars and the handicapped joined in the effort by donating all they had – twenty dollars, one hundred dollars – to a charitable organization. At the moment, it appeared they had donated everything they had and were suddenly left with nothing. But perhaps because of their act of kindness, they touched and inspired others, and ended up receiving many times more what they gave. When they made the donation, they were sincere in their wish to help and had no other intention in mind. As long as giving is done with true sincerity, the person who gives will unexpectedly receive in kind -- this is the amazing secret underlying cause and effect.

A person without renunciation only seeks satisfaction in this lifetime, and rebirth in the human or god realm; apart from being content with his lot in life, and getting by, he does not have a loftier goal. A person with renunciation may occasionally think the same way or enjoy good food, fine clothes, and a nice home. However, deep inside, he knows: this is not the purpose of my existence, merely a temporary lifestyle and means to an end which may or may not be necessary—my ultimate goal is to attain liberation. This way of thinking is basically considered renunciation. To sum up, a Vajrayana practitioner must first generate a heart of renunciation.

It is very important to know what mantra represents. Without a correct understanding of mantra, no matter how many times one recites the mantra, it can only alleviate negative karma caused by unwholesome words, but not gain any accomplishment. However, with the aforementioned right view, the effectiveness of applying mantra recitation to reduce negative karma, increase merit, and attain realization will be very different.

Likewise, it is stated in the scriptures that ripening of the cause comes in four types. The first is the one that ripens in the same lifetime. For example, karma was committed in youth and the effect takes place in middle or old age. Sometimes karma ripens even sooner, and the effect can be seen immediately. The reason is that certain conditions can expedite the manifestation of fruit. Such fast ripening has something to do with the object and the motivation of the action. There are many such cases told in One Hundred Stories about Karma (Karmasakata). For example, the Sangha and ordinary people are two completely different objects. If it is a serious case of stealing from or slandering the Sangha, the retribution may come right away or in this lifetime. If the same act is committed against ordinary people, one will surely bear the consequence but not necessarily right away or in this lifetime. The different results arise from the difference between the two objects. The other condition is the difference in motivation. If the intention to kill is very strong or has been premeditated for a long time, the retribution will come swiftly, whereas the effect may not be immediately apparent if the motivation to kill is not so fierce.

People think that desire motivates growth and development of mankind, a point that is not rejected by Buddhism either. It is said in the Mahayana scriptures that there must be self-grasping as great as Mount Sumeru in order to attain Buddhahood. Normally, self-grasping is condemned in Buddhism because it can cause greed, anger and delusion to arise. But here, it becomes the impetus to seek liberation; to certain extent, this is also a kind of desire. When desire to attain Buddhahood is absent, aspiration to learn Buddhadharm, to achieve enlightenment and to benefit sentient beings will not happen either. Genuine Dharma practice is a big, demanding and time consuming project that needs sufficient courage and drive to achieve its goal, and the source of this courage is the desire to attain Buddhahood. Arhats, lacking such desire, do not have the motivation to reach Buddhahood and hence seek only liberation for themselves.

Desire can be good or bad. Good desire is a driving force for Dharma practice and gaining enlightenment. Worldly desire, if unrestrained, can ruin a person.

True Buddhist practitioners are not pessimists even though they look upon money and fame as things of little value. This is because they are fully aware their spiritual development is not impaired by the body’s physical decline; wisdom and compassion will always follow them like a shadow in old age and even in death. Awaiting them from afar is a state of clarity and bliss; thus, far from being defeatist, they are optimistic and full of confidence. Because they have this aspiration, they can practice tirelessly and without regret. We need not fear suffering nor lose hope; with effort, we can free ourselves from the shackles of samsara and attain absolute happiness.

Without practice or mind training, we cannot be sure of attaining liberation. For instance, over the several decades in our lifetime, we do not in general have to worry about our livelihood; as long as we are willing to work, it is more or less guaranteed. However, death, this uninvited guest, comes when we least expect it. At the critical moment, we are not at all prepared to confront death or transform it into the path. Invariably, we are helpless when death arrives, so the question of birth, aging, illness, and death is a more important one than existence. If we cannot address this problem properly, it is more frightening than the struggle to stay alive; if we can come to terms with the problem in the correct way, it will be more meaningful than solving our livelihood. Therefore, practice is extremely important.

Nowadays, many lay people proclaim themselves to be students of the Buddha. But what of the Buddha have they learned? Most lay practitioners, ranging from intellectuals and business people down to the old ladies in the villages, practice the Dharma as a way of cultivating worldly blessings. Their motivation to practice, take refuge, and undertake the five precepts is to obtain good health, longevity, a smooth career, successful business, and so on for themselves, and a chance to enter a good university or get a promising job for their children. Are they following the way of the Buddha? The Buddha never did any of these. We all know that after the Buddha aroused bodhicitta, he never once sought worldly benefit for himself during the incalculable eons of three asamkhyeya kalpas. This mode of “learning the way of the Buddha” conforms more to learning the Dharma. The meaning of the Sanskrit word dharma encompasses all mundane and supramundane phenomena. In the context of practicing the right Dharma, dharma denotes an ability to deliver sentient beings from all suffering, and can be translated literally as “that which upholds.” It is in accord with the meaning of dharma if people practicing the Vehicle of Human and Celestial Beings enjoy the resulting blessings and take rebirth in the higher realms. Thus, undertaking virtuous deeds for the purpose of obtaining worldly benefits is not considered learning the Buddha’s way but learning the Dharma. Today, many self-proclaimed Buddhists maintain this kind of motivation.
