Silence is the only language of the realised. Practice moderation in speech. That will help you in many ways. It will develop love (prema), for most misunderstandings and factions arise out of carelessly spoken words. When the foot slips, the wound can be healed, but when the tongue slips, the wound that it causes in the heart of another will fester for life. The tongue is liable to four big errors: uttering falsehood, scandalising, finding fault with others, and excessive articulation. These have to be avoided if there has to be peace for the individual as well as for the society. The bond of brotherhood will be tightened if people speak less and speak sweetly. That is why silence was prescribed as a vow for spiritual aspirants by the spiritual texts. You are all spiritual aspirants at various stages of the road, so this discipline is valuable for you also. - Divine Discourse, Jul 22, 1958.
