In the first turning of the wheel of Dharma, the Buddha focused on the subjects in the outer preliminaries, suffering in samsara, infallible karma, etc., which are the four truths of Theravada Buddhism, not so much on emptiness; in the second turning of the wheel of Dharma, the Buddha also mentioned impermanence and suffering to some extent, but the heart of the teachings was emptiness; in the third turning of the wheel of Dharma, emptiness was no longer the most important, rather the luminous mind became the main topic the Buddha expounded.

Some students of Buddhism or other religions like to dwell on clairvoyant power and states of realization, but this is not the real purpose of Buddhism. Although Buddhism does not object to transcendent power, it does not chase after it. Buddhism mainly teaches how to cultivate compassion, develop wisdom, and serve others.

The worldview is firstly a specific knowledge; but more importantly, it is one of formulating this knowledge into ways and methods which can be used in our daily life. One aspect deals with regulating our own mind; the other aspect deals with benefiting sentient beings, bringing happiness, a healthy life, and joy to more people – this is also the basic tenet of Buddhism.

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.

Although freeing small fry or other beings that will not be killed in the near future is also liberating living beings, they are not lives saved at the point of being killed. To engender great merit and to be deemed a genuine form of fearless offering, lives saved should be those that are about to be killed such as the assorted fish sold in the marketplace.

When facing death, all the worldly wealth, knowledge, experience and so forth are rendered useless. Without prior training in preparation for one’s mortality, every person, however prominent his or her status in life is, will panic in the face of death. Many people become extremely pessimistic and despaired, turning gray-faced and gaunt in no time, after being diagnosed with advanced cancer and given the verdict of death by the doctors. Very often their fear is more detrimental to their condition than cancer itself.

The practice of the Four Noble Truths begins with the cultivation of renunciation and bodhicitta. Renunciation enables us to transcend samsara while bodhicitta inspires us to remain in samsara without being bound by it. Are they contradictory to each other? No, they’re not. If renunciation is not generated, samsara cannot be transcended. We will then end up in the same position as all other beings in the six realms, having no ability to save anyone. In order to transcend samsara, one must resolutely cut off all attachment to it. But that does not mean one should abandon all those remained in samsara afterwards. To abandon them means one’s goal is only to seek enlightenment for oneself and upon reaching that goal, one ignores their need for liberation. Sravakas and pratyekabuddhas, abiding in the meditation of cessation,¹ have transcended samsara and at the same time abandoned those left in samsara. Alas, owing to their limited power of samadhi, they neither have the ability nor the aspiration to lead other sentient beings to liberation.

Unlike greed and anger which are quite noticeable, ignorance is a latent defilement. When we are angry or being greedy, it is obvious to not only ourselves but also others because our behavior is different, whereas ignorance is hidden deep down and not easily detected. None of the wise and knowledgeable people in the world including scientists, philosophers and psychologists has yet to discover ultimate ignorance. Although various fields of study have helped us clear some delusions and revealed to us many truths about life and the world, ignorance, a defilement entrenched at the deepest level, has never been explored by either science, philosophy or religions. Moreover, as the methods provided by these disciplines are not counteractive to ignorance, they are unable to refute and end ignorance.

The first type of attachment is common to all sentient beings, including animals. As an example, from the time a building is constructed until such time it is demolished, we will think the building is a permanent structure which does not change. Even if there are changes to the building, we believe they are only superficial and not structural. In this and all other similar cases, the attachment which has no theoretical or empirical basis is innate or inherited at birth.
