If you yield to sense organs they are going to give you a lot of trouble. Right from the beginning you must find a way to bring them under absolute control. Then you will have accomplished something truly worthwhile, the real hero in this world is the one who has managed to completely control his senses. When the sense organs make their demands you should not listen to them. Instead, you should have your mind contact the intellect. Then whatever the intellect decides, the mind will command, and the sense organs will have to obey. That is the proper way to curb the senses. A person who bases his life on his lower mind will come to ruin and become worse than an animal. The wise one bases his life on his higher mind, his intellect, his powers of discrimination and discernment and intuition, what is called the Buddhi. One who follows his Buddhi becomes the most excellent of human beings. If you base your life on your Buddhi it will take you right up to the final goal. But, if you base your life only on the mind, then every moment new changes will come about and it will become difficult to predict what will happen to you and where you will land. It is something like crossing a raging river or a storm-tossed ocean in a small boat. You do not know when it will get flooded and when disaster will overtake you.

You must be careful until the very last breath of your life not to yield to the sense organs. To gain the Atma you must control the outgoing senses, therefore, sense-control is an integral; part of the path of wisdom which was taught by Krishna in the Samkhya Yoga. Once you gain full control of the senses, you will easily be able to master Bhakti Yoga, Karma Yoga, Jnana Yoga and all the other Yogas. (DBG, p. 116)

The first step in controlling the sense organs is to investigate the defects and problems associated with the various objects of the world. For the sake of temporary joys and pleasures, you are subjecting yourself to so many difficulties and problems, which will hound you long after the little fleeting joys, are forgotten. A person who has a disease may take some food items, which are not prescribed in the diet and feel temporarily happy. Having violated the diet and taken food, which is prohibited, he may experience some temporary joy; but in a short period of time he will experience the unhappy consequences of his acts. It may even lead to a dangerous situation. In the same way, man yielding to temporary joys, will suffer a great many problems in the long run. (DBG, p. 121)

A temple is usually situated within a compound having a protective wall around it in which there will be a number of gates or doors. The body can be thought of as a compound wall enclosing God, who resides in the temple of the heart, as the Atma. A temple would be constructed with the help of bricks, cement, sand and mortar, but this temple of the body is constructed out of blood, bones and flesh. In this wall of flesh and bones, there are also a number of gates or doors in the form of the sense organs. It is through these doors of the senses that desire and other qualities break in and invade the inner sanctuary. (ML, p. 310)
