As it is said:

kṛṣṇa — sūrya-sama; māyā haya andhakāra yāhāṅ kṛṣṇa, tāhāṅ nāhi māyāra adhikāra

Just as there is no chance that darkness can exist in the sunshine, in a pure Kṛṣṇa conscious person there can be no existence of māyā. The Lord Himself says in Bhagavad-gītā (7.14) :

daivī hy eṣā guṇamayī mama māyā duratyayā mām eva ye prapadyante māyām etāṁ taranti te

“This divine energy of Mine, consisting of the three modes of material nature, is difficult to overcome. But those who have surrendered unto Me can easily cross beyond it.” If one wants to be free from the influence of māyā, the illusory energy, one must become Kṛṣṇa conscious and always keep Kṛṣṇa prominent within the core of his heart. In Bhagavad-gītā (9.34) the Lord advises that one always think of Him ( man-manā bhava mad-bhakto mad-yājī māṁ namaskuru ). In this way, by always being Kṛṣṇa-minded or Kṛṣṇa conscious, one can surpass the influence of māyā ( māyām etāṁ taranti te ). Because Rantideva was Kṛṣṇa conscious, he was not under the influence of the illusory energy. The word svapnavat is significant in this connection. Because in the material world the mind is absorbed in materialistic activities, when one is asleep many contradictory activities appear in one’s dreams. When one awakens, however, these activities automatically merge into the mind. Similarly, as long as one is under the influence of the material energy he makes many plans and schemes, but when one is Kṛṣṇa conscious such dreamlike plans automatically disappear.
