We are full of ignorance
In a day there are many more akusala cittas than kusala cittas, but we are ignorant of them. When we do not perform dana, observe síla or apply ourselves to mental development, which comprises the development of calm and the development of right understanding, we think, act and speak with akusala cittas. There is often clinging after seeing, hearing, smelling, tasting or the experience of tangible object. We may not notice that there is clinging when it is subtle, but there are countless moments of them. Are we not attached to all the objects which are experienced through the six doors? Through satipatthana we gradually come to know the many moments of akusala citta, we come to know that we are thinking of ourselves more often than we ever thought.
