Swami says about how to control your speech :
Vak-suddhi (purity of speech) leads to mano-suddhi (purity of mind). That is why I insist on quiet talk, sweet talk and little talk, the sathwic talk; no anger, no heat, no hate. Such talk will cause no quarrel, no blood pressure and no factions. It will promote mutual respect and love. Then again do not cynically laugh at the good that others do or at the Sadhana of others. Inquire but do not insult. Respect the sincerity of the other man; respect also elders and men with more experience than you. In company, behave in a well-mannered way, showering brotherhood and joy on all around you. Sai Ram
