The Supreme Personality of Godhead declares that one who does not accept the proper treatment to detach the mind from material engagement can hardly achieve success in self-realization. Trying to practice yoga while engaging the mind in material enjoyment is like trying to ignite a fire while pouring water on it. Similarly, yoga practice without mental control is a waste of time. Such a show of yoga practice may be materially lucrative, but it is useless as far as spiritual realization is concerned. Therefore, the mind must be controlled by engaging it constantly in the transcendental loving service of the Lord. Unless one is engaged in Krsna consciousness, he cannot steadily control the mind. A Krsna conscious person easily achieves the result of yoga practice without separate endeavor, but a yoga practitioner cannot achieve success without becoming Krsna conscious.
