According to Krishnamurti ” …a  dialogue is very important, it is a form of communication in which question and answer continue till a question is left without an answer, thus the question is suspended between two persons involved in this answer and question. It is like a bud with untouched blossoms. If the question is left totally untouched by thought, it then has its own answer because the questioner and answerer as persons have disappeared. This is a form of dialogue in which investigation reaches a certain point of intensity and depth, which then has a quality which thought can never reach. It is not a dialectical investigation of opinions, ideas but rather an exploration by two or many serious, good brains.”

Periodic dialogues are held for  people to come together to explore, share and observe. A dialogue is usually preceded by a talk, a video screening or reading out an excerpt from the Teachings.
