So, these ordinary men who are influenced by the three modes of Nature can work out a plan of their sensual pleasure, but it is not possible for them to give authentic interpretations of Bhagavad-gītā as it was spoken by the Personality of Godhead to Vivasvān or Arjuna. The whole thing is received in transcendental submissiveness by aural reception, which is not accepted by the mundane wranglers deliberately refusing to approach the bona fide spiritual master who has got the keynote of Bhagavad-gītā. It is therefore stated in the Bhagavad-gītā that one who actually wants to have an access to the essence of Bhagavad-gītā must himself engage in the service of a bona fide spiritual master by full surrender. In that position only, one can make bona fide enquiries regarding the Bhagavad-gītā, and in that posture only, the self-realized spiritual masters impregnate the submissive disciple with the knowledge of Gītā, because they have already seen the Truth of it.
tad viddhi praṇipātena
upadekṣyanti te jñānaṁ
"Just try to learn the truth by approaching a spiritual master. Inquire from him submissively and render service unto him. The self-realized souls can impart knowledge unto you because they have seen the truth." [Bg. 4.34]
Mental speculationists can manufacture wonderful interpretations of Bhagavad-gītā by an intellectual activity, but such interpretation cannot be accepted as bona fide because that is not transcendental to the mundane senses, neither to the material mind in subtle state. As it is stated in the Bhagavad-gītā, such interpretations depending on the mind and senses are sure to be doomed like a boat on the troubled sea. It is said there:
indriyāṇāṁ hi caratāṁ
yan mano 'nuvidhīyate
tad asya harati prajñāṁ
vāyur nāvam ivāmbhasi
tasmād yasya mahā-bāho
tasya prajñā pratiṣṭhitā
yā niśā sarva-bhūtānāṁ
tasyāṁ jāgarti saṁyamī
yasyāṁ jāgrati bhūtāni
sā niśā paśyato muneḥ
samudram āpaḥ praviśanti yadvat
tadvat kāmā yaṁ praviśanti sarve
sa śāntim āpnoti na kāma-kāmī
vihāya kāmān yaḥ sarvān
pumāṁś carati niḥspṛhaḥ
sa śāntim adhigacchati
eṣā brāhmī sthitiḥ pārtha
naināṁ prāpya vimuhyati
sthitvāsyām anta-kāle 'pi
"As a boat on the water is swept away by a strong wind, even one of the roaming senses on which the mind focuses can carry away a man's intelligence.
Therefore, O mighty-armed, one whose senses are restrained from their objects is certainly of steady intelligence.
What is night for all beings is the time of awakening for the self-controlled; and the time of awakening for all beings is night for the introspective sage.
A person who is not disturbed by the incessant flow of desires—that enter like rivers into the ocean, which is ever being filled but is always still—can alone achieve peace, and not the man who strives to satisfy such desires.
A person who has given up all desires for sense gratification, who lives free from desires, who has given up all sense of proprietorship and is devoid of false ego—he alone can attain real peace.
That is the way of the spiritual and godly life, after attaining which a man is not bewildered. If one is thus situated, even at the hour of death, one can enter into the kingdom of God." [Bg.2.67-72]
By these presents it is not however meant that we shall have to accept somebody who is a professional spiritual master or a social spiritual master. The transcendentalist is one who has known Śrī Kṛṣṇa as He is. Śrī Kṛṣṇa is never the person Who can be conceived by mental or physical adjustment. He can only be known by those who have full surrender unto Him. He cannot be understood by sense perception because He is behind a curtain spread by yogamāyā. Unless that curtain is removed by the process of transcendental loving co-operation with Him, one cannot know Śrī Kṛṣṇa as He is.
nāhaṁ prakāśaḥ sarvasya
kaścid yatati siddhaye
yatatām api siddhānāṁ
kaścin māṁ vetti tattvataḥ
avajānanti māṁ mūḍhā
mānuṣĪṁ tanum āśritam
paraṁ bhāvam ajānanto
"I am never manifest to the foolish and unintelligent. For them I am covered by My internal potency." [Bg. 7.25]
"Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth." [Bg. 7.3]
"Fools deride Me when I descend in the human form. They do not know My transcendental nature as the Supreme Lord of all that be." [Bg. 9.11]
Śrī Vyasadeva experienced Śrī Bhagavān in the following way (Sanskrit quote).
