Upon seeing the devotion of the South Indian brāhmaṇa as he read the Gītā, Lord Caitanya embraced him and then told him that he had perfected the reading of the Gītā. What fool would deny that Lord Caitanya's approval is far superior to millions of university doctorates? This accolade from the Lord proves that the Bhagavad-gītā cannot be studied with material intelligence. The knowledge of the Gītā must be received through the chain of ācāryas, or spiritual masters, coming down in disciplic succession. That is the only method; otherwise studying the Gītā is an exercise in futility. The scriptural conclusion is that since the Supreme Lord is transcendental, His words are also transcendental, and hence the esoteric subject matter of the Bhagavad-gītā can be received only through a disciplic succession that is equally transcendental. As the Padma Purāṇa states,
- atah śrī-kṛṣṇa-nāmādi
- na bhaved grāhyam indriyaiḥ
- sevonmukhe hi jihvādau
- svayam eva sphuraty adaḥ
- (CC Madhya 17.136)
No one can understand the transcendental nature of the name, form, quality, and pastimes of Śrī Kṛṣṇa through his materially contaminated senses. Only when one becomes spiritually situated by transcendental service to the Lord are the transcendental name, form, quality, and pastimes of the Lord revealed to him.
This is confirmed in the Brahma-saṁhitā (5.38):
- premāñjana-cchurita-bhakti-vilocanena
- santaḥ sadaiva hṛdayeṣu vilokayanti
- yaṁ śyāmasundaram acintya-guṇa-svarūpaṁ
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
I worship Govinda, the primeval Lord, who is Śyāmasundara, Kṛṣṇa Himself with innumerable inconceivable attributes, whom the pure devotees see in their heart of hearts with the eye of devotion tinged with the salve of love.
Therefore, the scriptural conclusion is that mundane philosophers like Dr. Radhakrishnan are not qualified to delve into spiritual subjects. The devotees of the Lord alone are eligible to understand Lord Kṛṣṇa; no one else is qualified.
