Brahman indicates that the greatest is full with six opulences; the Supreme Personality of Godhead is the reservoir of all wealth, all fame, all strength, all beauty, all knowledge and all renunciation. When Lord Kṛṣṇa was present personally on earth, He exhibited these six opulences in full. No one was richer than Lord Kṛṣṇa, no one was more learned than Him, no one more beautiful, no one stronger, no one more famous and no one more renounced. Therefore the Supreme Personality of Kṛṣṇa is the Supreme Brahman. This is confirmed by Arjuna in Bhagavad-gītā (BG 10.12). paraṁ brahma paraṁ dhāma: "You are the Supreme Brahman, the ultimate, the supreme abode." Therefore Brahman indicates the greatest, and the greatest is the Supreme Personality of Godhead, Kṛṣṇa. He is the shelter of the Absolute Truth (para-tattva) because He is paraṁ brahma. There is nothing material in His opulences and exhibitions of wealth, fame, strength, beauty, knowledge and renunciation. All the Vedic verses and hymns indicate that everything about Him is spiritual and transcendental. Wherever the word Brahman appears in the Vedas, it should be understood that Kṛṣṇa, the Supreme Personality of Godhead, is indicated. An intelligent person at once replaces the word Brahman with the name Kṛṣṇa.
The Supreme Personality of Godhead is transcendental to the material modes of nature, but He is fully qualified with transcendental attributes. To accept the Supreme as impersonal is to deny the manifestation of His spiritual energies. When someone simply accepts the impersonal exhibition of spiritual energy to the exclusion of the Supreme Personality of Godhead, he does not accept the Absolute Truth in full. To accept the Supreme in full is to accept spiritual variegatedness, which is transcendental to the material modes of nature. By failing to indicate the Supreme Personality of Godhead, the impersonalists are left with an incomplete conception.
The approved method for understanding the Supreme Personality of Godhead, Kṛṣṇa, is the path of devotional service, and this is confirmed in every Vedic scripture. Devotional service of the Lord begins by hearing about Him. There are nine different methods in devotional service, of which hearing is the chief. Hearing, chanting remembering, worshiping—all these are used in the process of attaining the highest perfection by understanding the Supreme Personality of Godhead. This process by which the Supreme Personality of Godhead is understood is known as abhidheya, practice of devotional service within conditional life.
