CC Madhya 21.15
tvam api yad-antarāṇḍa-nicayā nanu sāvaraṇāḥ
kha iva rajāṁsi vānti vayasā saha yac chrutayas
tvayi hi phalanty atan-nirasanena bhavan-nidhanāḥ
This verse from Śrīmad-Bhāgavatam (10.87.41), which was spoken by the personified Vedas, is confirmed by Lord Kṛṣṇa in the Bhagavad-gītā (7.19):
bahūnāṁ janmanām ante jñānavān māṁ prapadyate
vāsudevaḥ sarvam iti sa mahātmā su-durlabhaḥ
“After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare.” Even after searching for the Absolute Truth throughout the universe, learned scholars and Vedic experts cannot reach the ultimate goal. In this way they come to Kṛṣṇa.
When there is a discussion about the Absolute Truth, there are always various pros and cons. The purpose of such arguments is to come to the right conclusion. Such an argument is generally known as neti neti (“not this, not that”). Until one comes to the right conclusion, the process of thinking “This is not the Absolute Truth, that is not the Absolute Truth” will continue. When we come to the right conclusion, we accept the Supreme Personality of Godhead, Kṛṣṇa, as the ultimate truth.
