Bhagavad Gita 3.6कर्मेन्द्रियाणि संयम्य य आस्ते मनसा स्मरन्।इन्द्रियार्थान्विमूढात्मा मिथ्याचारः स उच्यते ॥

The five organs of action, Karma Indriyas, are Vak (organ of speech), Pani (hands), Padam (feet), Upastha (genitals) and Guda (anus). They are born of the Rajasic portion of the five Tanmatras or subtle elements Vak from the Akasa Tanmatra (ether), Pani from the Vayu Tanmatra (air), Padam from the Agni Tanmatra (fire), Upastha from the Apas Tanmatra (water), and Guda from the Prithivi Tanmatra (earth). That man who, restraining the organs of action, sits revolving in his mind thoughts regarding the objects of the senses is a man of sinful conduct. He is selfdeluded. He is a veritable hypocrite.The organs of action must be controlled. The thoughts should also be controlled. The mind should be firmly fixed on the Lord. Only then will you become a true Yogi. Only then will you attain to Selfrealisation.
