Kṛṣṇa says, daivī hy eṣā guṇa-mayī mama māyā duratyayā (BG 7.14). Mama māyā. Māyā is under His control. Mayādhyakṣeṇa prakṛtiḥ (BG 9.10). Mayādhyakṣeṇa prakṛtiḥ. Prakṛti is working under His direction, under His superintendence. So we should know Kṛṣṇa like that. We should not.... Avajānanti māṁ mūḍhā mānuṣīṁ tanum āśritam (BG 9.11). Because He is speaking like a man, we are thinking that Kṛṣṇa came, and Kṛṣṇa is now dead, and His instruction is also dead, obsolete. No, that is not. Kṛṣṇa is ever-existing, nityo nityānām. We are also ever-existing. We are covered by this material body, but Kṛṣṇa is not covered by the material body. He comes in His original body. Sambhavāmy ātma-māyayā (BG 4.6). Yuge yuge sambhavāmy ātma-māyayā (BG 4.6). Paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām (BG 4.8). So Kṛṣṇa comes to save us and gives us His instruction so that after His disappearance from this world, people will take advantage of His instruction and make his life perfect. This is Bhagavad-gītā.
But if we misuse our intelligence and do not take advice from Kṛṣṇa and manufacture so many plans for prosperity, that will all fail. Moghāśā mogha-karmāṇo mogha-jñānā vicetasaḥ (BG 9.12). That is moghāśā. Mogha means frustrated. They will be frustrated. Moghāśā. Anyone who does not take the direction of Kṛṣṇa, then whatever he is hoping, that will be frustrated. Moghāśā mogha-karmāṇaḥ. And whatever he is planning, "I will do like this, he will do like that," that will not stay. Because the māyā is there. Daivī hy eṣā guṇa-mayī mama māyā duratyayā. Māyā will kill all your plans. Mām eva ye prapadyante māyām etāṁ taranti te (BG 7.14). And if you follow Kṛṣṇa and do accordingly, then you will not be frustrated. Your life will be successful. This is the philosophy of Bhagavad-gītā.
