Cetanā is a Pali word that means "intelligence". It is important to Buddhism because it is believed to be the main factor in achieving Enlightenment (liberation from suffering). We can use cetanā to help us make decisions about how we want to live our lives, so that we can find a path to happiness and peace. Cetanā encourages us to be wise and thoughtful in our decisions, so that we can make choices that lead to a better life.
