薄伽梵歌 9.19

我以太陽的形式散發熱量。我以因陀羅（Indra）的形式在雨季降雨，並在一年中的其餘時間收回雨水。「存在」（Sat）指顯現的世界（果）。「非存在」（Asat）指未顯現的（因）。非存在並不意味著虛無。微妙、未顯現的因被稱為非存在。自性或梵（Brahman）或永恆者絕不會完全非存在，它始終存在，是絕對的存在。如果你說微妙、未顯現的因是虛無，那麼從虛無中產生存在是不可想像的。《唱道奧義書》（Chhandogya Upanishad）問道：「存在如何能從非存在中產生？」認為存在源於非存在（虛無）簡直是荒謬的。對於吠檀多學派（Vedantin）的學生或追隨者來說，梵（絕對者）是「存在」（Sat），因為它始終存在且不變。這個顯現的世界是「非存在」（Asat）或不真實的。對於那些既不理解也不認識梵，心靈粗糙不純，缺乏敏銳微妙智慧，只能感知粗糙形式的世俗之人來說，這個顯現的世界是「存在」（Sat），而微妙、未顯現的原初本性（MulaPrakriti）——這個顯現世界的因——是「非存在」（Asat）。對他們來說，梵也是「非存在」（Asat）。未顯現的指原初本性（MulaPrakriti）和至高梵（Para Brahman），因為兩者都被隱藏。每個事物都有三種狀態：粗糙（Sthula）、微妙（Sukshma）和因果（Karana）。摩訶卡拉那（Mahakarana，偉大無因之因）是至高梵。粗糙和微妙狀態是因果的結果。你所見的外在是肉體，肉體由星光體（微妙體）驅動，星光體由心智、生命力（lifeforce）和感官組成。因果體是種子體，微妙體和粗糙體皆由此種子體產生。以橘子為例，外皮是它的肉體，內部的果肉或精華是微妙體，最內層產生果肉和外皮的因果體是種子。這只是一個粗略的例子，橘子還有另一種微妙體和因果體。世俗之人只看到肉體，並將其視為真理。對他們來說，星光體和因果體是不真實的。

I radiate heat in the form of the sun. I send forth the rain in the form of Indra in the rainy season and I take it back during the rest of the year.Sat Existence? the manifested world (the effect).Asat Nonexistence? the unmanifested (the cause).Nonexistence does not mean nothingness. The subtle? unmanifested cause is spoken of as nonexitence. The Self or Brahman or the Eternal can never be altogether nonexistence. It always exists. It is Existence Absolute. If you say that the subtle unmanifested cause is nothing? it is impossible to conceive existence coming out of nothing. The Chhandogya Upanishad asks? How can existence come out of nonexistence It is simply absurd to conceive that existence has arisen out of nonexistence (nothing).For a Vedantin ( student or follower of Vedanta) Brahman (the Absolute) is Sat (existence) because It always exists and because It is unchanging. This manifested world is Asat or unreal. For the worldlyminded people who have neither understanding nor knowledge of Brahman? who are endowed with gross and impure mind? who do not have a sharp and subtle intellect? and who ca perceive the gross forms only? this manifested world is the Sat and the subtle unmanifested MulaPrakriti (the primordial Nature)? the cause of this manifested world? is Asat. For them Brahman also is Asat. The unmanifested refers to MulaPrakriti and Para Brahman also because both are hidden.Every object has three states? viz.? the gross (Sthula)? the subtle (Sukshma) and the causal (Karana). Mahakarana (the great causeless cause) is Para Brahman. The gross and the subtle states are the effects of Karana. What you see outside is the physical body. This physical body is moved by the astral (the subtle) body made up of the mind? liferoce and the senses. The causal body is the seedbody. From this seedbody have sprung the subtle and the gross bodies. Take the case of an orange. The outer skin is its physical body the inner pulp or essence is the subtle body the innermost causal body which gives rise to the pulp and the outer skin is the seed. This is only a gross illustration. The orange has got another kind of subtle and causal bodies. The worldlyminded man beholds the physical body only and takes this as the Truth. For him? the astral and the causal bodies are unreal.
