Whenever you hear a spiritual teaching on a particular day, you will go about implementing it with a great deal of fervor and conviction; but only on that very day. But this is not the correct way to pursue your spiritual studies. You should use your intellect to understand the context in which you find yourself before you use words in a given situation. Whenever you do a particular thing or say something, you should know that truth is the royal means for reaching your ultimate goal. The tongue should not be tainted by untruth. The body should not be tainted by violence. The mind should not be stained by bad thoughts and bad feelings. It is only when you sanctify all these three, the tongue, the body and the mind and bring them into harmony, that you will be able to get the sacred vision of the Lord.
Students should be extremely careful in telling the truth. They should certainly tell the truth, but be careful not to go on talking and hurting others unnecessarily. Have control over your tongue. Whenever there is a misunderstanding with someone, if you tell him all his defects, with the justification that everything you are telling is true, then there are bound to be complications later. You should never hate others. When you have love in your heart, your words will naturally be very sweet. Even if anger develops, it will be of a fleeting nature.
There are four types of people. The anger of a person who is of a serene nature will be very short-lived; it recedes immediately. The Gita has declared such a one as a great soul. The second type will have this anger for a number of minutes, but it will soon fade away. The third category of person will have this anger continuously, all day long. The one in the lowest category will have this anger throughout his life.
