BG Chapters 7 - 12

The deluded interpreters neither surrender unto the lotus feet of Śrī Kṛṣṇa, nor teach others to follow this principle.

BG 7.15, Purport: The next class of duṣkṛtī is called māyayāpahṛta-jñānāḥ, or those persons whose erudite knowledge has been nullified by the influence of illusory material energy. They are mostly very learned fellows—great philosophers, poets, literati, scientists, etc.—but the illusory energy misguides them, and therefore they disobey the Supreme Lord.

There are a great number of māyayāpahṛta-jñānāḥ at the present moment, even amongst the scholars of the Bhagavad-gītā. In the Gītā, in plain and simple language, it is stated that Śrī Kṛṣṇa is the Supreme Personality of Godhead. There is none equal to or greater than Him. He is mentioned as the father of Brahmā, the original father of all human beings. In fact, Śrī Kṛṣṇa is said to be not only the father of Brahmā but also the father of all species of life. He is the root of the impersonal Brahman and Paramātmā; the Supersoul in every entity is His plenary portion. He is the fountainhead of everything, and everyone is advised to surrender unto His lotus feet. Despite all these clear statements, the māyayāpahṛta-jñānāḥ deride the personality of the Supreme Lord and consider Him merely another human being. They do not know that the blessed form of human life is designed after the eternal and transcendental feature of the Supreme Lord.

All the unauthorized interpretations of the Gītā by the class of māyayāpahṛta-jñānāḥ, outside the purview of the paramparā system, are so many stumbling blocks on the path of spiritual understanding. The deluded interpreters do not surrender unto the lotus feet of Śrī Kṛṣṇa, nor do they teach others to follow this principle.
