Certain religions like to stress the mysterious power of ghosts and spirits. Although Buddhism does not deny their existence, it believes the biggest demon in the world is the deeply embedded tendency to cling to the self. Outer demons can only affect our daily life in small ways, such as causing illnesses or obstacles. They cannot bind us in samsara, not even if the ghosts of the entire universe combine their forces. Only clinging to the self has such power. Yet, we have never realized that this fellow, Self, who abides in our mind at all times and whom we are very fond of, is really a demon.

People look at the same problem differently largely because of the state of their mind. Generally speaking, the mind of ordinary people is more fragile while that of the sages is strong. For instance, when the Buddha was about to enter parinirvana, he was surrounded by many arhats and practitioners. Although everyone knew the Buddha was dying and that they would lose not just a great but extraordinary teacher, all the arhats there were very calm. The exception was Ananda, who, having yet attained realization, was still an ordinary person. He stood crying by the side of the Buddha’s bed and could not contain his sorrow. The arhats were not disrespectful. Because they had already realized emptiness, they could pass beyond suffering.

However, neither the Nirmanakaya nor the Sambhogakaya is the true Buddha, only the Dharmakaya, the union of wisdom and compassion, is.

We must understand that the six realms of samsara are not invented or arranged by the Creator or any personified god. Nor are they some chance happenings, devoid of causes and conditions. They are in fact the manifestations of cause and effect. And the most important cause among all is clinging to the self.

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"

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.

In Beacon of Certainty, the original face of suffering is said to be pure like the sky above the high plateau in Tibet, just emptiness. The great sage Atisha also said in his commentaries on the Middle Way that the nature of mind is clear and unobstructed like the autumn sky. What is perceived as suffering has long since dissolved into clouds of smoke; there are no traces of it left.

Among the four schools of Buddhism, Sarvastivada1 and Sautrantika did not maintain any idealistic viewpoints at all, neither did the Madhyamaka (Middle Way) school of the Mahayana tradition.

The Yogachara (Consciousness Only) school of Mahayana had a number of sects, of those only one posited a small portion of its views that was somewhat similar to that of idealism.

However, we cannot simply count on reason or theory to gain certainty in this view; we need to let the mind rest and examine it during meditation. Free the mind from discursive thoughts; neither review the past nor invite the future. The past no longer exists, the future has yet to come; if there is a mind, it can only be the mind at the present moment. Let us then check to see if the present mind exists. If we have been diligent in our practice of the preliminaries, we would know, in the instant we examine the mind, that the mind at this very moment is none other than clarity and emptiness.
