Even great demigods like Brahmā are bewildered in their speculative attempts to understand the Supreme Personality of Godhead. Each philosopher is covered by a unique combination of the modes of nature and thus describes the Supreme Truth according to his own material conditioning. Therefore even strenuous empirical endeavor will never bring one to the conclusion of all knowledge. The highest knowledge is Kṛṣṇa, the Supreme Personality of Godhead, and one can understand Him only by fully surrendering to Him and serving Him with love. This is why Mārkaṇḍeya Ṛṣi states here, vande mahā-puruṣam: “I simply worship that Supreme Personality.” Those who try to worship God but at the same time continue speculating or acting fruitively will attain only mixed and bewildering results. To be pure a devotee must give up all fruitive activity and mental speculation; in that way his loving service to the Lord will yield perfect knowledge of the Supreme. Only this perfection can satisfy the eternal soul.
Thus end the purports of the humble servants of His Divine Grace A.C. Bhaktivedanta Swami Prabhupāda to the Twelfth Canto, Eighth Chapter, of the Śrīmad-Bhāgavatam, entitled “Mārkaṇḍeya’s Prayers to Nara-Nārāyaṇa Ṛṣi.”
