The Buddha taught that heedlessness ... - Dhamma by Ajahn Jayasāro
The Buddha taught that heedlessness (pamāda) is the path to death, and heedfulness (appamāda) is the path to the deathless.
Heedfulness is such an important virtue that it the teaching emphasised by the Buddha in the last words he spoke before he left the world. Heedfulness means keeping ourself awake to the truths of our body and mind, and of the world around us. It means not allowing ourself to forget that youth, health and life itself are unreliable and uncertain. It means not taking anything or anyone for granted.
In family life, heedfulness means finding the time to take care of the quality of our most important relationships: being mindful of how we act towards those we live with, how we speak to them, and how we hold them in our thoughts
