Māyā will never allow such person to understand the real thing. They will go on making plan-making; it will be frustrated. Again plan-making, again frustrated, again frustrated.
So this process is going on because they do not know that their self-interest is that Supreme Personality of Godhead. Therefore Kṛṣṇa says that He comes, He descends, with two purposes: paritrāṇāya sādhūnām (BG 4.8), to give relief to the pious, to the righteous; and to vanquish the miscreants, and to establish the real religious principle.
And what is that real religious principle? That is stated in the last instruction: sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is real religion, to surrender unto the Supreme Personality of Godhead. That's all. This is done even by great philosophers. He has to do that. Bahūnāṁ janmanām ante (BG 7.19)
