Among all means of suppressing lawlessness I am punishment, and of those who seek victory I am morality. Of secret things I am silence, and of the wise I am the wisdom.
There are many suppressing agents, of which the most important are those that cut down miscreants. When miscreants are punished, the agency of chastisement represents Kṛṣṇa. Among those who are trying to be victorious in some ﬁeld of activity, the most victorious element is morality. Among the conﬁdential activities of hearing, thinking and meditating, silence is most important because by silence one can make progress very quickly. The wise man is he who can discriminate between matter and spirit, between God’s superior and inferior natures. Such knowledge is Kṛṣṇa Himself. Bhagavad-gītā As It Is 10.38
Of the descendants of Vṛṣṇi I am Vāsudeva, and of the Pāṇḍavas I am Arjuna. Of the sages I am Vyāsa, and among great thinkers I am Uśanā.
Kṛṣṇa is the original Supreme Personality of Godhead, and Baladeva is Kṛṣṇa's immediate expansion. Both Lord Kṛṣṇa and Baladeva appeared as sons of Vasudeva, so both of Them may be called Vāsudeva. From another point of view, because Kṛṣṇa never leaves Vṛndāvana, all the forms of Kṛṣṇa that appear elsewhere are His expansions. Vāsudeva is Kṛṣṇa's immediate expansion, so Vāsudeva is not different from Kṛṣṇa. It is to be understood that the Vāsudeva referred to in this verse of Bhagavad-gītā is Baladeva, or Balarāma, because He is the original source of all incarnations and thus He is the sole source of Vāsudeva. The immediate expansions of the Lord are called svāḿśa (personal expansions), and there are also expansions called vibhinnāḿśa (separated expansions). Amongst the sons of Pāṇḍu, Arjuna is famous as Dhanañjaya. He is the best of men and therefore represents Kṛṣṇa. Among the munis, or learned men conversant in Vedic knowledge, Vyāsa is the greatest because he explained Vedic knowledge in many different ways for the understanding of the common mass of people in this Age of Kali. And Vyāsa is also known as an incarnation of Kṛṣṇa; therefore Vyāsa also represents Kṛṣṇa. Kavis are those who are capable of thinking thoroughly on any subject matter. Among the kavis, Uśanā, Śukrācārya, was the spiritual master of the demons; he was an extremely intelligent and far-seeing politician. Thus Śukrācārya is another representative of the opulence of Kṛṣṇa. Bhagavad-gītā As It Is 10.37
