Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam, buddhi-yogaṁ dadāmi tam (BG 10.10). Kṛṣṇa says that "I give him intelligence." To whom? Satata-yuktānām, those who are engaged twenty-four hours. In which way he is engaged? Bhajatam, bhajana, those who are engaged in devotional service. What kind of devotional service? Prīti-pūrvakam, with love and affection. One who is engaged in devotional service of the Lord in love and devotion. What is the symptom of love? The symptom, the prime symptom, most important symptom of love is that the devotee wants to see that his Lord's name, fame, etc. become widespread. He wants to see that "My Lord's name be known everywhere." This is love. If I love somebody, I want to see that his glories are spread all over the world. And Kṛṣṇa also says in the Bhagavad-gītā, na ca tasmāt manuṣyeṣu kaścit me priya-kṛttamaḥ, anyone who preaches His glory, nobody is dearer to Him than that person.
Everything is there in the Bhagavad-gītā, how you can love, what are the symptoms of love, how you can please God, how He can talk with you, everything is there. But you have to take advantage. We read Bhagavad-gītā, but by reading Bhagavad-gītā I become a politician. So what kind of reading Bhagavad-gītā? Politician is there, of course, but the real purpose of reading Bhagavad-gītā is to know Kṛṣṇa. If one is Kṛṣṇa, if one knows Kṛṣṇa, he knows everything. He knows politics, he knows economics, he knows science, he knows philosophy, he knows religion, he knows sociology, everything. Tasmin vijñāte sarvam etaṁ vijñātaṁ bhavanti, that is the Vedic injunction. If you simply understand God, Kṛṣṇa, then everything will be revealed to you because Kṛṣṇa says, buddhi-yogaṁ dadāmi tam. If Kṛṣṇa gives you intelligence from within, who can excel Him? Nobody can excel Him. But Kṛṣṇa can give you intelligence provided you become a devotee, or lover of Kṛṣṇa. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam, buddhi-yogaṁ dadāmi tam BG 10.10. And what is that buddhi-yoga, what is the value of buddhi-yoga? That buddhi-yoga or bhakti-yoga, the value is yena mām upayānti te. Such buddhi-yoga, such intelligence will get him back to home, back to Godhead. Not that by such intelligence he will go down to hell. That is material intelligence.
Adānta-gobhir viśatāṁ tamisram SB 7.5.30. Everything is discussed in Bhāgavatam. For the materialist person, adānta-gobhi. Adānta means unbridled, uncontrolled. Go means indriya or senses. Materialistic persons, they cannot control their senses. They are servant of the senses, godāsa. Go means indriya, and dāsa means servant. So when you come to the position of controlling the senses, then you'll be gosvāmī. That is gosvāmī. Gosvāmī means controlling the senses, who has completely controlled the senses. Svāmī or gosvāmī. Svāmī also means that and gosvāmī also means the same thing. Generally adānta-gobhir viśatāṁ tamiśram. Uncontrolled senses, they are going. It is not that Kṛṣṇa is sending them. He is making his own path clear, either back to home, back to Godhead, or glide down to the darkest region of hell. Two things are there, and that opportunity is in the human form of life. You can select. Kṛṣṇa, as He inquired from Arjuna, whether "Your illusion has been dissipated."
