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.

Bardo Tödröl elucidates the whole process of death, the state of after-death and the process of taking rebirth. The book has received rather strong support in the West mainly because its contents have been validated by many near-death experiences of people who came back to life after a sudden death. The fact that the ancient text of Bardo Tödröl happens to match the clinical findings of modern medicine accounts for its great stature and influence. You should read the book if you are interested in knowing more about it.

Why do we “watch the mind from the side” and not directly? If we watch the mind directly, the mind will be startled and disturbed, unable to rest quietly. If we proceed to watch the mind directly as soon as it enters a state of no- self, we will destroy that state since the thought of watching the mind is itself a kind of distraction. When that happens, the original state of tranquility disappears. As for watching the mind from the side, the mind can remain at rest and, at the same time, bring into full play its ability to supervise; as soon as distraction sets in, it will know and pull it back in place.

To liberate lives is a common practice frequently performed by many Buddhists. When conducted properly, the resulting merit is boundless. Otherwise, the merit will be greatly diminished. It is therefore very important for us to know the proper way of liberating living beings.

All the activities of a bodhisattva can be put into six different categories, that is, the six paramitas or the six perfections. In other words, the bodhisattva’s view, conduct, practice and activities of benefiting and delivering sentient beings are vast like the ocean, but all can be summed up in the six paramitas.

What does it mean to watch the mind directly? For instance, if there is a thought to examine whether the mind is calm or thinking of other things, it is watching the mind directly. We should not entertain this kind of examination when abiding in the concentrated state, because once the thought of examination arises, it disrupts this state. Hence we need to watch the mind from the side.

When our whole body is dissected and the parts are piled up, let us take a look: I have always believed in the existence of a “self,” but where is this “self”? Am I this muscle? Am I this pile of skin, or strand of hair? Am I this type of fluid — blood, lymph, etc.? No, there is no “self” besides these body parts.

 A lot of people opt for a life in the middle whereby there is neither great suffering nor happiness – a relatively placid life in which they can also practice the Dharma. However, an ordinary life such as this is not necessarily long-lasting. We cannot avoid the eight types of suffering, including birth, aging, illness, and death, and may even encounter great vicissitudes in life. Without the Dharma, how do we confront these circumstances?

According to tantra, sentient being is buddha, buddha is sentient being; samsara is nirvana, nirvana is samsara. The basic nature of samsara and nirvana is the same, but because we are not yet enlightened and still have afflictions, we see buddha and sentient being, wisdom and afflictions, separately as pure and impure. The tantric path is called Vajrayana because of this view; it is unique in this sense.

Although non-Buddhist beliefs also proclaim some notion of emptiness, they are unable to enunciate the void nature of all phenomena based on dependent origination. Their idea of emptiness is only some sort of simple emptiness, unlike the one that is inseparable from phenomena. For example, some non-Buddhists also point out that what we see with our eyes and hear with our ears is all illusory. However, most of their ideas about emptiness are just nothingness which ignore phenomena altogether. This is neither the emptiness taught by Nagarjuna and other like-minded masters, nor the one expounded by Asanga and the like that is inseparable from luminous clarity. Emptiness of non- Buddhism means simply non-existence, just like human heads are without horns, which is not the true meaning of Buddhist emptiness. But non-Buddhist idea of emptiness, regretful to say, is just this simple.
