So now Kṛṣṇa is summarizing in this verse... Because the whole manifestation, tathedam akhilaṁ jagat, the whole universe is presentation of the energy of the Lord, therefore there is nothing but Lord. Mattaḥ parataraṁ nānyat (BG 7.7). Just like in this material world, we have got experience, the sun is the cause of all material manifestations. When the sunlight or sun heat... Just like Western countries, in this season, the sunlight and heat is practically not present. Therefore it is snowfall. There is no foliage in the trees. Every tree is deserted, due to the sun. And as soon as from the month of April the sunshine will be little more, mean, increased, at once the leaves will come out. In the Western world, this experience... Anywhere. The sun is the cause of everything, all this material world. So you can say that in this material world, there is nothing superior energy than the sun. Similarly, this is also a creation of God, the sunshine. It is stated in the Brahma-saṁhitā: yac cakṣur eṣa savitā sakala-grahāṇām. Savitā means sun.
- yac cakṣur eṣa savitā sakala-grahāṇāṁ
- rājā samasta-sura-mūrtir aśeṣa-tejāḥ
- yasyājñayā bhramati sambhṛta-kāla-cakro
- govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
Even the sun, which is the supreme cause of this material world, of this universe... All the planets, they are rotating on account of heat of the sun. If the sun moves little this side or that side, everything will be blazing fire or frozen into ice. This is scientific truth.
So as the sun is the supreme cause of this material world, similarly the supreme cause of... There are many millions of universes and millions of suns. They are all caused by the supreme energy of Kṛṣṇa, bhūmir āpo 'nalo vāyuḥ and apareyam itas tu viddhi me prakṛtiṁ parām (BG 7.4). Two prakṛtis, parā-prakṛti and aparā-prakṛti. So the Vedānta-sūtra, that janmādy asya yataḥ (SB 1.1.1), the original source of everything, Brahman, that is Kṛṣṇa. Therefore Kṛṣṇa says, mattaḥ parataraṁ nānyat (BG 7.7). Brahman is not supreme. Then Kṛṣṇa would have said not... "Brahman is the Supreme." But He says, mattaḥ parataraṁ nānyat. Brahman is the bodily effulgence of Kṛṣṇa. Yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). Brahman is not the supreme cause. Brahmaṇo 'haṁ pratiṣṭhā. Brahman is existing on Kṛṣṇa. Therefore Kṛṣṇa says, Kṛṣṇa has the right to say, mattaḥ parataraṁ nānyat: "There is no more superior cause." And in the Brahma-saṁhitā, Lord Brahmā also says, sarva-kāraṇa-kāraṇam (Bs. 5.1).
- īśvaraḥ paramaḥ kṛṣṇaḥ
- sac-cid-ānanda-vigrahaḥ
- anādir ādir govindaḥ
- sarva-kāraṇa-kāraṇam
- (Bs. 5.1)
So it is not that Kṛṣṇa is saying only. It is accepted by the supreme Vedic authority, Lord Brahmā.
