Prabhupāda: So pratikāram and apratikāram. Whatever we have manufactured, pratikāram, counteraction, that will be also failure if Kṛṣṇa does not sanction it. That is realized by Prahlāda Mahārāja. He says “My dear Lord,” Hiraṇyakaśipu, that “people have manufactured so many pratikāram, counteraction.” But tanu-bhṛtām, “Those who have accepted this material body, they are simply manufacturing things to counteract dangers. But even though they have all this counteracting machine or counteracting agents, still, without Your sanction, this counteracting machine or agent will not be fruitful.” So similarly, Arjuna is being protected by Kṛṣṇa. So even though Arjuna is not well-equipped, apratikāram, still he will be saved. Because Kṛṣṇa is there. Tāvad vibho tanu-bhṛtāṁ tvad-upekṣitānām (SB 7.9.19). And even one is well-equipped and if Kṛṣṇa does not like to save him, he’ll not be saved. Always mind this. Rakṣe kṛṣṇa mare ke, mare kṛṣṇa rakṣe ke. This is ordinary, that if Kṛṣṇa wants to kill you, nobody can save you. And if Kṛṣṇa wants to save you, nobody can kill you. This is the position.
Therefore real pratikāram is Kṛṣṇa. Real pratikāram is Kṛṣṇa, counteractive. So better we take shelter of Kṛṣṇa as Kṛṣṇa says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). You must always know that no counteraction will be beneficial for us unless we are protected by Kṛṣṇa. So therefore our business is fully surrender to Kṛṣṇa and seek His protection. Kṛṣṇa says, “Yes,” ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi, “I shall give you protection.” This is Bhagavad-gītā philosophy. We have to believe on the assertion of Kṛṣṇa that “He is prepared to give me all protection, provided I have fully surrendered unto His lotus feet.”
