The mind has two aspects: one is discriminating mind, or “discriminating thought”; the other is non-discriminating mind, or “non-discriminating thought.”

The eye, ear, nose, tongue, and body have feeling, but they do not reflect or contemplate; so these feelings are called nondiscriminating thought. When we are sick, regardless of what we are thinking, our body experiences a great deal of suffering; this is non-discriminating thought.

When we see and hear something, the sixth consciousness reflects and distinguishes between the good and the bad; this is called “discriminating thought.” The suffering experienced by the sixth consciousness is called the suffering of discriminating thought.

The Buddha’s primary goal of teaching was to communicate precisely the doctrine of the Three Dharma Seals to the listeners. Failing this, the teaching would have been pointless. What made the Three Dharma Seals so important?  The answer is in the sutras. A disciple once asked the Buddha, “How can the real teachings be distinguished if the non-Buddhists try to deceive with their false version after you, The Blessed One, pass into nirvana?” The Buddha answered, “Any teaching, as long as it espouses the principles of the Three Dharma Seals, can be considered Buddhist teaching; otherwise, it is not Buddhist teaching.” The fact that the Buddha always emphasized the key points in his transmissions should explain why so much importance has been attached to the Three Dharma Seals.

Renunciation and bodhicitta should be practiced separately in proper order and followed by the practice of emptiness. As such, renunciation and bodhicitta that were practiced beforehand will also turn into the wisdom of emptiness.

Here, emptiness is not like the Theravada view of no-self. Rather, it contains the element of great compassion. And within great compassion, there is realization of emptiness. These views and practices of the union of wisdom and compassion encompass all the implicit significance of the Dharma. However, they are much easily said than done.

- Quote from The Right View, "Buddhism—the Definition"

There is suffering everywhere in the six realms of rebirth: if not suffering of suffering, it is suffering of change; if not suffering of change, it is all-pervasive suffering. This is especially so in this degenerate time. Even if we are unwilling to accept suffering, all of us have to confront it; we cannot ignore it.

Human beings do not have methods for facing suffering, thus they hope for happiness and are afraid of suffering. Animals are the same way — they hope bad things go away and that good things come quickly. A whole life is hence wasted in this expectation.

Buddhism holds that a glass of water seen by sentient beings of the six realms will manifest six different phenomena, respectively. By the same token, beings of the six realms will see six different worlds, somewhat like the idea of the multiverse.

- Quote from The Right View, "Buddhism—the Definition"

Renunciation is the foundation of bodhicitta. Having aroused bodhicitta, one is qualified to receive the bodhisattva vows which one can bestow on oneself. Afterwards, one can begin the practice on emptiness. Knowing that the union of wisdom and compassion is the combination of emptiness and bodhicitta essentially means that one has understood perfectly the quintessence of all the exoteric and esoteric teachings of Mahayana Buddhism.

- Quote from The Right View, "Buddhism—the Definition"

When suffering or happiness arises, changes in brain wave activity in certain parts of the brain are detected. Thus some people believe suffering and happiness are produced by the brain. Actually, the brain is only a tool. Consciousness is dependent on the brain to discern and experience external phenomena, but suffering and happiness are not produced by the brain.

The sutras have often discussed and demonstrated that suffering comes from self-attachment, that is, attachment to the existence of a self. Here, the conclusion is set forth from a different standpoint. Suffering and happiness are not produced by external circumstances, but are closely related to our views and habitual tendencies. All suffering is created by our own attachment to things.

Renunciation depends on the practice of the four general preliminaries, that is, the conviction of the rarity and preciousness of human birth and impermanence of all phenomena must be generated. For bodhicitta to be aroused, there must be sufficient amount of merit accumulated through mandala offering and obscurations purified and healed by meditation on Vajrasattva. Clearly, one cannot avoid undertaking the practice of general and extraordinary preliminaries no matter how one chooses to go on the path. This is also the reason why I have been insisting all along on the necessity of preliminary practice.

- Quote from The Right View, "Buddhism—the Definition"

The Buddha himself once said that there were quite a few inconsistencies in his teachings in order to suit the taste of different audience, but the one that would never change is the teaching on emptiness.  For example, from the point of view of relative truth, impermanence and suffering being the nature of all phenomena are deemed absolute truth, but not from the point of view of the ultimate truth. In the Three Dharma Seals, only no-self is deemed the absolute truth.
