Prabhupāda: Always remember that this Kṛṣṇa consciousness is a sort of declaration of war with this illusory material nature. So there is war. She will always try to get you fall down. Daivī hy eṣā guṇa-mayī mama māyā duratyayā (BG 7.14). It is very strong, powerful. How you can save yourself? Mām eva ye prapadyante māyām etāṁ taranti te. If you persistently simply adhere to the devotional service of Kṛṣṇa, there will be no more strength of this illusory nature to drag you. No more. There will be no more power to get you into this province of sense gratification. Material nature means the jurisdiction of sense gratification. That's all. Simply people are engaged by sense gratification like cats and dogs. That's all. This is material atmosphere. And in the spiritual atmosphere there is no sense gratification; there is only activity for satisfying the Supreme, Kṛṣṇa. That is the difference.
So if you adherently be always engaged in some sort of service, twenty-four hours in the service of the Supreme Lord Kṛṣṇa in Kṛṣṇa consciousness, there is no power in the world who can drag you into this sense gratification province. You at once become nirguṇa. This is the process. So we have to stick to this principle: "How I can serve Kṛṣṇa always, always?" Īhā yasya harer dāsye. If you cannot do, if you simply think, "How can I do? How can I do? How can I do?" simply this, if you practically cannot do, but if you simply think that "How can I do?" oh, then also you become liberated. Then also you become liberated. And what to speak of when we actually serve. This is such a nice thing, Kṛṣṇa consciousness. So if you want to save yourself from this material turmoil, then always stick to this Kṛṣṇa consciousness persistently. Yes.
