These externally very attractive news, we should avoid it completely. We shall simply talk of Kṛṣṇa. That is the safest method. We shall simply talk kṛṣṇa-kathā. And kṛṣṇa-kathā means what Kṛṣṇa has said. That is kṛṣṇa-kathā. Or what is spoken about Kṛṣṇa. So Bhagavad-gītā means kṛṣṇa-kathā, what Kṛṣṇa has said. And Śrīmad Bhāgavatam is also kṛṣṇa-kathā because everything said about Kṛṣṇa. So we don't We should not indulge in grāmya-kathā. That will mislead us. And if we do not indulge in grāmya-kathā, but if we make advancement on Kṛṣṇa-kathā, then we are always situated on transcendental position. We are no more affected by the modes of material nature. Sa guṇān samatītyaitān brahma-bhūyāya kalpate (B.G.14:26). So we should stick to this principle. Then we shall be saved. Otherwise, either I become man or woman, we are all condemned because we are implicated with grāmya-kathā.
(Lecture on Srimad Bhagavatam----6:1:64-65).

Because neophyte devotees cannot understand what the forms of Nārāyaṇa, Vāsudeva and Govinda are, Kṛṣṇa directly says, mām ekam. Herein, this is also supported by the word kṛṣṇa-padāravindayoḥ. Nārāyaṇa does not speak personally, but Kṛṣṇa, or Vāsudeva, does, as in Bhagavad-gītā for example. Therefore, to follow the direction of Bhagavad-gītā means to surrender unto Kṛṣṇa, and to surrender in this way is the highest perfection of bhakti-yoga.
(Srimad Bhagavatam----6:1:19----purport)

This is a very important verse. Even big scholars cannot understand Kṛṣṇa, yet they dare comment on the Bhagavad-gītā. Reading the Bhagavad-gītā means understanding Kṛṣṇa, yet we actually see many scholars making blunders in trying to understand Kṛṣṇa. Gopīnātha Ācārya's statement is confirmed in many places in the Vedic literature.
(Sri Caitanya Caritamrta----2:6:87----purport).

The Second Chapter is the summary study of the Bhagavad-gītā. The First Chapter is the preparatory study of Bhagavad-gītā, and the Second Chapter is the summary study of the contents of Bhagavad-gītā. Bhagavad-gītā means the song sung by the Supreme Personality of Godhead. Bhagavata. From the word bhagavata, we speak Bhagavān.
(Lecture on Bhagavad-Gita----2:13).

So we are beginning today speaking on Bhagavad-gītā, the preliminary scientific study of this science of Godhead. Bhagavad-gītā means Bhagavān, the Supreme Personality of Godhead. Bhagavān means the Supreme Personality of Godhead. Bhaga, we generally know, bhāgya, opulence, fortune, a man is called bhāgyavān. This bhāgyavān word comes from the word bhaga, Bhagavān. Bhaga means opulence, six kinds of opulences: wealth, strength, influence, education, wisdom, beauty, and renunciation. These are opulences. If a man is wealthy, he's attractive. He attracts. Any man, very wealthy, he attracts.
