Ignorance is translated in Chinese as "wu ming." The word "ming", refers to wisdom that comes from realization; "wu" is a negation. Thus, wu ming means the absence of wisdom and the absence of realization. Although the innate clarity of the mind is always there, we have never recognized or experienced it because we have not attained realization. This is why it is called ignorance.

Mahayana Buddhism calls for transcendence, not desertion, of samsara. The bodhisattvas practice emptiness, not-self, or great compassion not to escape from the suffering of samsara but to benefit sentient beings more thoroughly and effectively, and to serve the needs of others more generously. Ordinary people, unable to break loose from samsara, have no choice but to remain trapped in the cycle of rebirth. Whereas the bodhisattvas, no longer being bound by samsara, choose to remain because sentient beings only exist in samsara, not in nirvana. In order to deliver sentient beings from all suffering, the bodhisattvas must work from within, not out of, samsara. The key to understand this dichotomy lies in distinguishing between the relative truth and the absolute truth.

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.

If the purpose of doing something was to satisfy worldly pursuits such as health and longevity, it would be deemed an unwholesome motivation. All the activities done on this premise, whether they are meditation or reciting sutras, are considered just mundane phenomena that do not lead to enlightenment. Patrul Rinpoche had said that absent genuine renunciation and bodhicitta, if one were to do a nine-year retreat and cut off all associations with others to practice the Great Perfection full-time, one would not even sow the seed of liberation, let alone other achievements. How terrible having not generated renunciation and bodhicitta! What use is there for other practices when not even the Great Perfection can sow the seed of liberation? Therefore, making the choice of motivation should never be taken lightly.

Broadly speaking, the view, the practice and the behavior of non-Buddhist traditions and those of Buddhism are all different, and so are their results. The key difference lies in whether or not they include taking refuge in the Three Jewels—the Buddha, Dharma and Sangha. One that does so is Buddhism; otherwise, it is non-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 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.

The word “religion” came from the West. If defining Buddhism by way of the meaning of religion, Buddhism cannot be deemed exactly a religion as the word “religion” comprises in itself the recognition of a supernatural power or powers as the creator and governor of the universe, which Buddhism dissents. Some in the West do not see Buddhism as religion because of this. Those learned and respectable Buddhist practitioners in the past also held the same opinion. I too do not see Buddhism fit the Western definition of “religion” as Buddhism has never acknowledged the existence of the Creator.

Excerpt from Luminous Wisdom Book Series : The Right View ~ Buddhism – The Definition

The Four Noble Truths explain the nature, the origin, the cessation and the path leading to the cessation of suffering. Why are there not three or five truths? It is because all that is known or exists can be assigned to either samsara or nirvana; there is no other kind of existence in between. Samsara has its cause and effect; so does nirvana. Two sets of cause and effect make the Four Noble Truths. To explain nirvana and samsara by way of cause and effect is essentially what the Four Noble Truths are all about.

Although Vajrayana requires its practitioners to accept five meats and five nectars as part of the practice, beginners must stay away from them and use instead visualization or some herbal medicine as substitutes. If not, plainly eating meat and drinking alcohol will create huge demonic obstacles to one’s practice. What does it mean by demonic obstacle? On hearing this term, many people instantly picture a human or non-human being with eyes, ears, multiple heads and hands. These actually are just petty demons. The king of demons that would obstruct our practice is none other than the habit of eating meat. Such is the view of Vajrayana. So who says that eating meat is permissible with Vajrayana?
