Say what you mean and mean what you say. In many wisdom traditions the ‘word’ is regarded as sacred and all-powerful. Many forms of mysticism, from the highest types of meditation and prayer, to the lower forms of elemental magic and modern teachings on ‘manifestation’ based on some understanding of the subconscious mind, rely on focused usage of sacred or meaningful words. In the New Testament, John’s gospel makes direct reference to the power of the ‘Word’ in the ultimate spiritual sense. Psychologically, good communication in life is essential for success and well-being. That does not mean that we mechanically ‘tell the truth’ in all circumstances in life.
Some circumstances may require us to be Gurdjieff’s ‘sly man’, a man who can adapt to circumstances and when necessary, ‘do in Rome as the Romans do’ (for example, not needlessly upsetting a very young child by telling them Santa is not real or burdening your old and dying grandparent with useless ‘honest’ information). But as a rule of thumb, truthfulness in life accords with living a life of power and integrity. A man who habitually speaks out of both sides of his mouth is rarely trustworthy.
The most recommended mode of communication for men—especially with other men—is straight and direct. Bluntness, without being gratuitously rude, is also masculine and when tinged with good will or humor can be very effective. Direct communication, the vast majority of times, is more helpful for others—and ourselves—than avoidance, triangulation (going through someone else), or sugar-coating. More to the point, make your own word in life count. Do not commit to something unless you are reasonably sure about your decision, but when you do, make your commitment count.
