Nature and the living entities are sometimes designated as prakṛti and puruṣa respectively. The whole cosmic manifestation is an amalgamation of prakṛti and puruṣa. Nature is the ingredient cause, and the living entities are the effective cause. These two causes combine together, and the effect is this cosmic manifestation. When one is fortunate enough to come to the right conclusion about this cosmic manifestation and everything going on within it, he knows it to be caused directly and indirectly by the Supreme Personality of Godhead Himself. It is concluded in the Brahma-saṁhitā, therefore, īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ / anādir ādir govindaḥ sarva-kāraṇa-kāraṇam (Bs. 5.1). After much deliberation and consideration, when one has attained the perfection of knowledge, one comes to the conclusion that Kṛṣṇa, or God, is the original cause of all causes. Instead of speculating about the measurement of God—whether He is so long or so wide—or falsely philosophizing, one should come to the conclusion of the Brahma-saṁhitā: "Kṛṣṇa, or God, is sarva-kāraṇa-kāraṇam (Bs. 5.1), the cause of all causes." That is the perfection of knowledge.
Thus the Veda-stuti, or the prayers offered by the personified Vedas to Garbhodakaśāyī Viṣṇu, were first narrated in disciplic succession by Sanandana to his brothers, all of whom were born of Brahmā at the beginning of the universe. The four Kumāras were the first-born sons of Brahmā; therefore they are known as pūrva-jāta. It is stated in the Bhagavad-gītā that the paramparā system, or the disciplic succession, begins with Kṛṣṇa Himself. Similarly, here, in the prayers of the personified Vedas, it is to be understood that the paramparā system begins with the Personality of Godhead Nārāyaṇa Ṛṣi. We should remember that this Veda-stuti is narrated by Kumāra Sanandana, and the narration is repeated by Nārāyaṇa Ṛṣi in Badarīkāśrama. Nārāyaṇa Ṛṣi is the incarnation of Kṛṣṇa for showing us the path of self-realization by undergoing severe austerities. In this age Lord Caitanya demonstrated the path of pure devotional service by putting Himself in the role of a pure devotee. Similarly, in the past Lord Nārāyaṇa Ṛṣi was an incarnation of Kṛṣṇa who performed severe austerities in the Himalayan ranges. Śrī Nārada Muni was hearing from Him. So in the statement given by Nārāyaṇa Ṛṣi to Nārada Muni, as narrated by Kumāra Sanandana in the form of the Veda-stuti, it is understood that God is the one supreme and that all others are His servants.
