According to the early Buddhist analysis of existence, craving, or tanhā, is the very root cause of the samsāric predicament, being the central factor responsible for the arising of dukkha, as highlighted in the second noble truth. Due to its pivotal role as the chief cause of bondage, tanhā features in numerous passages and contexts in the early discourses…
The term “tanhā” literally stands for “thirst”…Tanhā - as a figurative type of thirst that demands the satisfaction of desires - manifests as a sense of lack or want, and has its root in dissatisfaction. Various aspects of craving are reflected in the use of a range of imageries and similes in the discourses.
One such image speaks of being enmeshed by craving, of being caught in the net of craving. … The net imagery recurs in relation to craving in general in a verse in the Theragāthā (Verses of the Elders), which compares the condition of one who has destroyed the net of craving … to the stainless moon on a clear night. The Dhammapada also employs this imagery, when it contrasts the net-like nature of craving to the freedom attained by the Buddha who, in contrast to such forms of entrapment, has a limitless range.
The aspect of craving as a form of bondage, …which underlies the net imagery, recurs in other similes. Overcome by craving, beings run around in circles comparable to a rabbit caught in a snare. Covered by craving’s cloak, they are in bondage like a fish in a trap.
…Another set of images revolves around the theme of growth in nature. These images alert us to the danger of allowing craving to follow its natural course, thereby becoming forever stronger. This aspect can be seen in a Dhammapada verse that compares the fertility of the underlying tendency to craving to a tree that grows again after being cut down. Similarly, as long as its roots are left intact, craving will grow again. Hence craving together with its root need to be removed.
