[Advayavada Study Plan – week 17] Man is basically prone to existential suffering (dukkha, duhkha) because he wrongly strives after and tries to hold on to things, concepts and situations which he believes to be permanent, but are not. His mistaken view of things is produced by a thirst, craving or clinging (tanha in Pali, trishna in Sanskrit) which is in turn caused by his fundamental ignorance (avijja in Pali, avidya in Sanskrit) or disbelief of the true nature of existence, especially its changeability and selflessness or emptiness. This is the second noble truth of Buddhism, and this thirst, craving or clinging can moreover easily take on a more unwholesome form: already as sensuous desire, ill-will, laziness, impatience or distrust will it seriously hinder the individual’s efforts to better his or her circumstances, as well as contaminate the efforts of others to improve theirs.
