So Arjuna also showed by example. Although he was talking as friend, he submitted to Kṛṣṇa, śiṣyas te 'haṁ śādhi māṁ prapannam (BG 2.7). Arjuna was talking directly with Kṛṣṇa. But because the relationship was affectionate friendship, there could not be any serious talk. Therefore Arjuna submitted that "Kṛṣṇa, we are talking like friends; it will never come to any serious. Now I accept You as my guru." Śiṣyas ye 'haṁ śādhi māṁ tvāṁ prapannam. Kārpaṇya-doṣopahata-svabhāvaḥ (BG 2.7): "I am now perplexed." So when one is actually in knowledge, he feels perplexed. Athāto brahma jijñāsā. Unless one feels perplexed in this materialistic way of life, his human life is imperfect. One must feel that this material world, actually it is not happiness. Just like Sanātana Gosvāmī approached Caitanya Mahāprabhu that grāmya-vyavahāre paṇḍita, satya kari māni (CC Madhya 20.100): "I am minister, I am also born of a brāhmaṇa family." In India the brāhmaṇas are addressed as paṇḍitjī. So he says, grāmya-vyavahāre paṇḍita kaha ei paṇḍita: "Just like ordinary relationship, village friendship, they call me paṇḍita." Paṇḍita means learned. "I also accept that I am paṇḍita. But actually I am not paṇḍita." Why not? Āpanāra hitāhita kichui nāhi jāni: "I do not know what is the goal of my life." Ask anyone what is the goal of life. He may be Ph.D., D.A.C., he does not know. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). They do not know.
Therefore if one is serious about understanding the value of life, the goal of life, he should approach a guru. Tasmād guruṁ prapadyeta (SB 11.3.21). Prapadyeta. Prapadyeta means to surrender. Not that guru should be approached for challenging. No. If you challenge, then you'll be cheated. First of all, you must find out a person who, if you can surrender there. Tasmād guruṁ prapadyeta. Tad viddhi praṇipātena (BG 4.34). Praṇipāt, surrender, that is required first. If you think somebody that he's not worth surrendering, then don't make him guru. Don't make a fashion. First of all you test that "Whether I can surrender?" Praṇipātena. Then try to understand. Tad viddhi praṇipātena paripraśnena sevayā. Not only surrendering, but also render service so that guru may be pleased that "This disciple is very humble, meek and giving service." Anywhere, even in material world, if you want to take something from somebody, if you please him by service, it is very easy. Tasmād guruṁ prapadyeta jijñāsa (SB 11.3.21).
So, yathā hi puruṣasyeha viṣṇoḥ padopasarpaṇam yadā eṣa sarva-bhūtānām. Why one should seek after Viṣṇu? Tad viṣṇoḥ paramaṁ padam. Because yadā eṣa sarva-bhūtānāṁ priya. Everyone's dearmost. That we have forgotten. Actually Viṣṇu, or Kṛṣṇa, He's dearmost. He's also friend of everyone. When we understand this secret, bhoktāraṁ yajña-tapasāṁ sarva-loka-maheśvaraṁ suhṛdaṁ sarva-bhūtānām (BG 5.29). Suhṛdam: He's actual friend. We go to friends for some help, but if we accept the natural friend, Kṛṣṇa, then there is no scarcity. Suhṛdam sarva-bhūtānām. Therefore we should learn how to love Kṛṣṇa, or Viṣṇu. That is the aim of life.
