Understanding Impermanence (Anicca)

My readings on Anicca and death have led me to the following very concise paragraph, found here:

The word Anicca means impermanence. Another word often jointly used by the Buddha is "viparinamadhammo "-- meaning "the nature of change." Impermanence or change is a fundamental concept in Buddhism. Without a realization of it there can never be any rather true insight through which we can see things as they really are.

The Buddha teaches that we can only understand Dukkha and Anatta through an understanding of Anicca. The Buddha however has chosen Dukkha as the central point of a realization of the truth. This choice is a very skillful method of explaining the realities of life.

It is the knowledge of Anicca, impermanence, that heals Dukkha, suffering. By understanding Anicca, we come to understand that there is no permanent entity underlying our life (Anatta).

A lack of this right understanding will certainly result in finding oneself in the wild jungle of perverted perception, polluted thought and tainted view (Sanna, citta, ditthivipallasa). A failure to comprehend this truth, Anicca, will also leave one unprotected from the false notion of self or soul which dangerously underlies any wrong view.
