Śrīla Prabhupāda Says - [Regarding how Kṛṣṇa consciousness means to fight against māyā]

There are so many reasons one may fall down. Not only... Actually, the reason is māyā. Māyā, māyā. It is a fight. To take to Kṛṣṇa consciousness means it is a fight against māyā. Māyā is trying to keep you captivated within this material world. But if anyone takes to Kṛṣṇa consciousness, he, māyā has to give him up. Māyā cannot control anymore. That is not the jurisdiction of māyā.

Because you have read in the Bhagavad-gītā that Kṛṣṇa says, daivī hy eṣā guṇamayī mama māyā duratyayā: [Bg. 7.14] "It is very, very, very difficult to get out of the grip of the strong māyā." It is not... But mām eva ye prapadyante: "If anyone comes to Me or surrenders unto Me," māyām etāṁ taranti te [Bg. 7.14], "he immediately becomes out of the jurisdiction of māyā." So māyā is strong always.

Just like I was explaining this morning what is māyā. Māyā is already there, side by side, Kṛṣṇa and māyā. Just like this light. This side is light; this side is darkness. Take this example. This light, the one side is very bright; another side is dark. So this darkness and this light is always side by side. Similarly, Kṛṣṇa and māyā... Because māyā is one of the energy of Kṛṣṇa.

When Vyāsadeva by bhakti-yoga meditation experienced the whole thing, what did he see? He saw Kṛṣṇa. Apaśyat puruṣaṁ pūrṇam: "He saw the Supreme Person." Māyām ca tad-apāśrayam: "And he saw also māyā on the back side." Just like when you, if you stand, the light side, your shadow is not on the light side. The light... The shadow is on the back side.

So in our back side the māyā is there, although you are in front of Kṛṣṇa. So as soon as you become little slack in Kṛṣṇa consciousness, immediately māyā is ready to capture you. Māyā is always going side by side. As Kṛṣṇa is all-pervading, the māyā is also all-pervading. As soon as there is lack of Kṛṣṇa consciousness, there is immediately māyā.
