Man should first strive for sense control. We must keep our tongue, taste, smell, hearing and sight under control. I often tell our boys to see that they do not have drishti dosha (faulty vision). When you see an object, you go on thinking about the same object. After sometime, you develop a desire to possess that object. When you hear something, you go on thinking about it. Later, you desire to have that object. When you speak something, you will try to substantiate your opinion with some proof. Therefore, whatever you speak, whatever you hear, whatever you see, you must ensure that it is faultless. If you really want to attain divinity, you must be free from the pancha dosha (five faults), namely, (1) vaag dosha (speaking bad words), (2) drishti dosha (seeing bad things), (3) kriya dosha (doing bad deeds), (4) shravana dosha (hearing bad words) and (5) mano dosha (thinking bad thoughts). If you are able to remove these pancha dosha (five faults) from your personality, you will become Paramatma verily. Man should keep his tongue under control. This is the first and foremost sadhana. The reason being, the tongue has two powers. The eye has only one power of seeing an object. The ear has only one power of hearing. Similarly, the nose has only one power of identifying the smell. But, the tongue can talk as well as feel the taste. Therefore, it must always be engaged in divine activities. (BG Part II, p. 48-49)
