"If we want to be aloof from the contamination of this material world, then everything, whatever we use, whatever we need, it must be in relation with Kṛṣṇa. Then we can keep ourself aloof from the contamination. That is the liberated condition. That means you are eternal servant of Kṛṣṇa. If you always be engaged in the service of the Kṛṣṇa, then you are above this material world, uncontaminated. But if you have got any material intention, then again you are under the clutches of māyā. We should always remember it."
(Srila Prabhupada Lecture, Delhi, November 16, 1971)
