BG Chapters 7 - 12

BG 9.34, Purport:

One should cultivate the knowledge of Kṛṣṇa continuously. What is that favorable cultivation? It is to learn from a bona fide teacher. Kṛṣṇa is the Supreme Personality of Godhead, and we have several times explained that His body is not material, but is eternal, blissful knowledge. This kind of talk about Kṛṣṇa will help one become a devotee. Understanding Kṛṣṇa otherwise, from the wrong source, will prove fruitless.

SB Canto 2

SB 2.7.43-45, Purport:

In the Upaniṣads it is clearly said that the Supreme Personality of Godhead can never be known simply by working very hard and taxing the good brain, nor can He be known simply by mental speculation and jugglery of words. The Lord is knowable only by one who is a surrendered soul. Herein Brahmājī, the greatest of all material living beings, acknowledges this truth. Therefore, the fruitless spoiling of energy by pursuing the path of experimental knowledge must be given up. One should gain knowledge by surrendering unto the Lord and by acknowledging the authority of the persons mentioned herein. The Lord is unlimited and, by the grace of the yogamāyā, helps the surrendered soul to know Him proportionately with the advance of one's surrender.

SB Canto 3

SB 3.5.41, Purport:

All Vedic knowledge is meant for understanding the Supreme Lord, as stated by the Lord in Bhagavad-gītā (15.15): vedaiś ca sarvair aham eva vedyaḥ. Intelligent persons, who are like swans, take shelter of the Lord by all means and do not hover on the mental plane by fruitlessly speculating on different philosophies.

SB 3.6.38, Purport:

There are some froggish philosophers who want to know the Supreme Soul by means of philosophy and mental speculation. And when the devotees, who are to some extent in knowledge of the Supreme Lord, admit that the glories of the Lord are inestimable or inconceivable, the froggish philosophers adversely criticize them. These philosophers, like the frog in the well who tried to estimate the measurement of the Pacific Ocean, like to take trouble over fruitless mental speculation instead of taking instructions from devotees like the original poet, namely, Brahmā. Lord Brahmā underwent a severe type of meditation for one thousand celestial years, yet he said that the glories of the Lord are inconceivable. Therefore what can the froggish philosophers hope to gain from their mental speculations?
