Purport

In this Seventh Chapter of Bhagavad-gītā, the nature of Kṛṣṇa consciousness is fully described. Kṛṣṇa is full in all opulences, and how He manifests such opulences is described herein. Also, four kinds of fortunate people who become attached to Kṛṣṇa, and four kinds of unfortunate people who never take to Kṛṣṇa are described in this chapter. 

In the first six chapters of Bhagavad-gītā, the living entity has been described as nonmaterial spirit soul which is capable of elevating himself to self-realization by different types of yogas. At the end of the Sixth Chapter, it has been clearly stated that the steady concentration of the mind upon Kṛṣṇa, or in other words Kṛṣṇa consciousness, is the highest form of all yoga. By concentrating one’s mind upon Kṛṣṇa, one is able to know the Absolute Truth completely, but not otherwise. Impersonal brahmajyoti or localized Paramātmā realization is not perfect knowledge of the Absolute Truth because it is partial. Full and scientific knowledge is Kṛṣṇa, and everything is revealed to the person in Kṛṣṇa consciousness. In complete Kṛṣṇa consciousness one knows that Kṛṣṇa is ultimate knowledge beyond any doubts. Different types of yoga are only steppingstones on the path of Kṛṣṇa consciousness. One who takes directly to Kṛṣṇa consciousness automatically knows about brahmajyoti and Paramātmā in full. By practice of Kṛṣṇa consciousness yoga, one can know everything in full—namely the Absolute Truth, the living entities, the material nature, and their manifestations with paraphernalia. 

One should therefore begin yoga practice as directed in the last verse of the Sixth Chapter. Concentration of the mind upon Kṛṣṇa the Supreme is made possible by prescribed devotional service in nine different forms, of which śravaṇam is the first and most important. The Lord therefore says to Arjuna, “tat śṛṇu,” or “Hear from Me.” No one can be a greater authority than Kṛṣṇa, and therefore by hearing from Him one receives the greatest opportunity for progress in Kṛṣṇa consciousness. One has therefore to learn from Kṛṣṇa directly or from a pure devotee of Kṛṣṇa—and not from a nondevotee upstart, puffed up with academic education. 

In the Śrīmad-Bhāgavatam this process of understanding Kṛṣṇa, the Supreme Personality of Godhead, the Absolute Truth, is described in the Second Chapter of the First Canto as follows: 

śṛṇvatāṁ sva-kathāṁ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ
hṛdyantaḥstho hy abhadrāṇi vidbunoti suhṛt satām.

naṣṭa-prāyeṣv abhadreṣu nityaṁ bhāgavata-sevayā
bhagavaty uttama-śloke bhaktir bhavati naiṣṭhikī.

tadā rajas-tamo-bhāvāḥ kāma-lobhadayaś ca ye
ceta etair anāviddhaṁ sthitaṁ sattve prasīdati.

evam prasanna-manaso bhagavad-bhakti-yogataḥ
bhagavat-tattva-vijñānaṁ mukta-saṅgasya jāyate.

bhidyate hṛdaya-granthiś chidyante sarva-saṁśayāḥ
kṣīyante cāsya karmāṇi dṛṣṭa evātmanīśvare.

“To hear about Kṛṣṇa from Vedic literatures, or to hear from Him directly through the Bhagavad-gītā, is itself righteous activity. And for one who hears about Kṛṣṇa, Lord Kṛṣṇa, who is dwelling in everyone’s heart, acts as a best-wishing friend and purifies the devotee who constantly engages in hearing of Him. In this way, a devotee naturally develops his dormant transcendental knowledge. As he hears more about Kṛṣṇa from the Bhāgavatam and from the devotees, he becomes fixed in the devotional service of the Lord. By development of devotional service one becomes freed from the modes of passion and ignorance, and thus material lusts and avarice are diminished. When these impurities are wiped away, the candidate remains steady in his position of pure goodness, becomes enlivened by devotional service and understands the science of God perfectly. Thus bhakti-yoga severs the hard knot of material affection and enables one to come at once to the stage of ‘asaṁśayaṁ samagram,’ understanding of the Supreme Absolute Truth Personality of Godhead.” (Bhāg. 1.2.17-21)plugin-autotooltip__small plugin-autotooltip_bigŚrīmad Bhāgavatam 1.2.17

Śrī Kṛṣṇa, the Personality of Godhead, who is the Paramātmā [Supersoul] in everyone's heart and the benefactor of the truthful devotee, cleanses desire for material enjoyment from the heart of the devotee who has developed the urge to hear His messages, which are in themselves virtuous when properly heard and chanted.
 

Therefore only by hearing from Kṛṣṇa or from His devotee in Kṛṣṇa consciousness can one understand the science of Kṛṣṇa.
