The second type is suffering arising from change. This type of suffering is not obvious at the outset, but may turn into something rather painful later on. For instance, if we see a stranger die of a car accident on the street, we probably will not feel too distraught with grief. However, if the deceased should turn out to be our parent or a loved one, our grief would be very strong and immediate because of the emotional attachment we have to the person. Frankly, we would not have suffered had suffering not been a latent part of family relationship already. Besides, worldly happiness can also turn into a source of suffering. For example, the happy gathering of friends and relatives gives one pleasure, but the eventual parting makes one sad. If there had been no feeling of happiness at the gathering, there would not have been any sadness at the time of parting. Thus, happiness is in direct proportion to suffering here. Suffering arising from change may appear to be happiness on the surface, but can in fact turn into suffering at any moment. That is to say, without earlier happiness, no suffering will ensue either, just like we never feel happy or sad about meeting and leaving the strangers at the malls or other public places. Since we did not experience happiness in the first place, no suffering will ensue afterwards. Suffering arising from change is so named because the ensuing suffering concealed within prior happiness will eventually reveal itself when conditions change.

- Quote from The Right View, "The Four Noble Truths—the Path Out of Samsara"

What needs to be overthrown is our steadfast clinging to the belief of distinct, self-existing phenomena, not the standpoints of the atheists or some other philosophies. Once that clinging is gone, nothing that others preach can impair our true view anymore. For no matter how eloquent they are, they cannot affect someone who has realized emptiness. The means by which one can thoroughly destroy clinging to the idea of self-existing phenomena is to generate renunciation, arouse bodhicitta and cultivate the critical view of emptiness.

Why is realization of emptiness so powerful? It is because the cause of our endless rebirth in samsara is not something external but our own views and attachment, a kind of thought actually. And thoughts can be overthrown, but not all of them. Those that are formed on a solid base with logical reasoning are very difficult to be overthrown.

Is clinging to the idea of a real self well grounded and sensible? Not so. Ever since birth, we have always had this notion of a self. Now take a look and see if this self truly exists. And how does it exist? If we examine closely, we will discover that it does not exist. But why do we have this compelling sense of a real self? The truth is that it is all just an illusion. Like when running a high fever, one may see hallucinations as real or have strange thoughts popped up in mind. This is because the causes for seeing hallucinations or having twisted thoughts are already formed such that whatever one sees or thinks is nothing but the illusions created by these causes.
