In the sutras, suffering of change is defined as not having a feeling of suffering when things are progressing; however, when they end, a feeling of suffering arises.

This suffering is found primarily in the human and god realms. The gods here refer to those in the desire realm.

For instance, the gods in the desire realm enjoy good health, long life, and favorable living conditions; they also have certain supernatural powers. There is a sense of happiness under these circumstances; however, when this so-called “happiness” comes to an end, it is followed by distinct and unbearable suffering. One must know the feeling of well-being up front and the great suffering that follows are somewhat related.

Why is the word “suffering” repeated? This alludes to the great intensity of the suffering. That aspect of suffering which all living beings, whether human or animal, perceive alike and reject, and which is clearly recognized as a painful feeling, is said to be suffering of suffering. This suffering is found primarily in the lower three realms; it is also evident in the human and god realms, for example, in the eight basic types of suffering of human beings such as birth, aging, sickness, and death.

- Quote from The Four Seals of Dhama, "All Contaminated Things are Unsatisfactory"

We are accustomed to thinking all matter undergo the three stages of becoming, abiding, and cessation. But in this microcosm, we cannot experience arising and ceasing at all; arising and ceasing simply do not exist. Arising is ceasing; ceasing is arising.

This principle, contrary to the conventional view, shows the so-called notion of becoming, abiding, and cessation is a complete misconception. In Buddhism, it is known as “momentary arising and ceasing”; in modern physics, it is called “motion in a microcosm.”

Some people run into problems when they practice contemplating samsara is suffering. I’ve come across people who go to extremes: before they do the practice, they are confident about life, their work, and the world, and feel good about everything; however, after doing the practice, the world turns grey, they lose interest in everything and become extremely passive and listless — to the point of seeing no meaning in life at all.

Is renunciation the same as passivity and pessimism? No, it would be a mistake to think so.

Just as bodhicitta is more than mere compassion, it is, with compassion as the base, the resolve and courage to attain Buddhahood in order to liberate all sentient beings; renunciation is more than just apprehending samsara is suffering, it is also the determination to seek liberation for oneself.

- Quote from The Four Seals of Dhama, "All Contaminated Things are Unsatisfactory"

Presently, there are many empowerments and teachings given on Dzogchen and Vajrayana Buddhism; there are also many people who claim they want to practice Dzogchen and receive empowerments. However, serious practitioners of impermanence and bodhicitta are few and far between. This is why we never see progress. We are true practitioners only if we earnestly undertake basic practices like impermanence and suffering. At that point, our worldview will be entirely different; however difficult or harsh life’s circumstances, there will be nothing we cannot think through and accept.

- Quote from The Four Seals of Dhama, "All Phenomena Lack Self-Existence"

Impermanence can be divided into two kinds, inner and outer. The world of living beings, the sentient world, is referred to as “inner,” the physical world of mountains and rivers, the non- sentient world, as “outer.” Each kind of impermanence can be further classified as continuous or momentary.

- Quote from The Four Seals of Dhama, "All Phenomena Lack Self-Existence"

A Buddhist practitioner must first be able to see through the vanity of money, fame, etc. To “see through” is to know these things fade like the cloud and smoke, and that none are worth pursuing. Of course, even if we have this understanding today, we may not be able to give them up right away. The Buddha did not expect us to do so either; even if he did, we would not be able to comply. Nonetheless, the inability to forgo these things does not imply samsara is not suffering, nor does it suggest we cannot give them up in the future.

- Quote from The Four Seals of Dhama, "The Importance of Practice "

The Three Dharma Seals are not only the view of Sakyamuni Buddha but also that of all the buddhas of the ten directions and three times. Any buddha that turns the wheel of Dharma will expound the Three Dharma Seals. All that is transmitted pertains to the Three Dharma Seals; in whatever manner the teachings are given, their essence is the Three Dharma Seals, even in Vajrayana Buddhism. Although the uncommon view of Vajrayana speaks of emptiness and clarity, it also espouses impermanence, suffering, etc. at the same time.

- Quote from The Four Seals of Dhama, "Summation"

Indeed, even the slogans on the main roads say “We live but once!” but in fact this is not so. As sentient beings with strong karmic imprints, we will continue to take rebirth in samsara over countless lifetimes; however, without practice, we will only end this life in spiritual decline. As you know, beings who take rebirth in the lower realms – even in the most favorable animal realm – do not have a chance to practice Dharma, let alone hear the sacred designations and mantras of the buddhas. Beings in the hungry ghost and hell realms are even less likely to have this chance. Therefore, however busy or difficult it may be, we must still seize the moment to practice. If we forgo this most propitious opportunity, we cannot be sanguine about coming back as human beings again.
