BG Chap 10 - The vibhūtis of Kṛṣṇa - 46 thru 50

(46): Among types of knowledge, He is knowledge of the soul. The four Vedas with its six aṅgas, mīmāṁsā, nyāya, dharma śāstra and purāṇas are considered the fourteen types of knowledge. The six aṅgas are: Śikṣa (pronunciation), chandas (meter), vyākaraṇa (grammar), nirukta (meaning), jyotiṣa (astrology) and kalpa (ritual). Nyāya refers to logic such as Gautama’s Nyāya. Mīmāṁsā refers to both Karma Mīmāṁsā and Vedānta. Among these types of knowledge, Kṛṣṇa is knowledge concerning ātmā, the knowledge of Vedānta, which has four chapters, and which defines Paramātmā and His associates. The first chapter of Vedānta shows Brahman as the subject of the Vedas. The second chapter solves all contradictions between the statements of different scriptures. The third chapter deals with sādhana for attaining Brahman. The fourth chapter describes the attainment of Brahman.
(47): Among types of debate, Kṛṣṇa is vāda. Vāda, jalpa and vitaṇḍa are famous as the three types of argument. When both parties desire to win by establishing their own opinion with false proofs and arguments, and by refuting the opponent’s view with circumvention (chala), false generalization (jāti) and syllogistic fault (nigraha-sthāna), it is called jalpa. When one party refutes the opponent’s view (by the above means), without establishing his own opinion, it is called vitaṇḍa. These two types of debate, with a desire to win, simply display skill in debating and bear no result. That discussion having a desire for truth is called vāda. Vāda uses proper logic and pramāṇas, takes into consideration both points of view, in order to arrive at the truth. Being outstanding for being fruitful in determining truth, vāda is Kṛṣṇa’s vibhūti.
(48): Among letters, Kṛṣṇa is the letter ‘A’. A-kāra, the first letter of the Sanskrit alphabet, is the beginning of the Vedic literature. Without a-kāra, nothing can be sounded; therefore it is the beginning of sound.
(49): Among compound words, He is the dvandva or the dual compound, in which both elements have equal importance, e.g. rāma-kṛṣṇa. The other compounds are: avyayībhāva, in which the first element is more important – e.g. adhyātma (adhi ātmā), in the soul; tat-puruṣa, in which the second element is more important – e.g. guṇātita (guṇa atita), surpassing the guṇas; bahu-vrīhi in which both elements are unimportant depending on reference to a third element – e.g. mahā-bahuḥ, one who has strong arms.
(50): Among destroyers, Kṛṣṇa is indestructible time, which according to Baladeva Vidyābhūṣaṇa is the fire of universal destruction emanating from the mouth of Saṅkarṣaṇa, and according to Viśvanātha Cakravarti is Mahākāla, Rudra, who is famous as the destroyer.
