There are many learned sages, philosophers and transcendentalists who try to conquer the senses, but in spite of their endeavors, even the greatest of them sometimes fall victim to material sense enjoyment due to the agitated mind. Even Viçvämitra, a great sage and perfect yogé, was misled by Menakä into sex enjoyment, although the yogé was endeavoring for sense control with severe types of penance and yoga practice. And, of course, there are so many similar instances in the history of the world. Therefore, it is very difficult to control the mind and the senses without being fully Kåñëa conscious. Without engaging the mind in Kåñëa, one cannot cease such material engagements. A practical example is given by Çré Yämunäcärya, a great saint and devotee, who says: "Since my mind has been engaged in the service of the lotus feet of Lord Kåñëa, and I have been enjoying an ever new transcendental humor, whenever I think of sex life with a woman, my face at once turns from it, and I spit at the thought."
