Adhikaraṇa 4
Brahman Is The Only Original Cause
The saṅkhya theorist raises another doubt: "It cannot be said that the Vedānta
describes Brahman as the sole cause of the universe, for the Vedānta philosophy
does not describe a single original cause of creation. In Taittirīya Upaniṣad 2.1.1
ātma (self) is revealed as the source of creation in the following words:
tasmād vā etasmād ātmana ākāśaḥ sambhūtaḥ
"From ātmā the sky was born."
Another passage (Tatittirīya Upaniṣad 2.7.1) describes asat (non-existence) as
the original cause in the following words:
asad vā idam agra āsīt tato vā sad ajāyata tad ātmānaṁ svayam akuruta
"In the beginning was non-existence. From non-existence existence was born.
Existence created the self."
Another passage (Chāndogya Upaniṣad 1.9.1) affirms that ākāśa (sky) is the
original cause:
asya lokasya kā gatir ity ākāśa iti hovāca
"What is the origin of this world? Sky is the origin, he said."
Another passage (Chāndogya Upaniṣad 1.11.5) affirms that breath is the
original cause in the following words:
sarvāṇi ha vā imāni bhūtāni prāṇam evābhisaṁviśanti
"Everything was born from breath and ultimately enters into breath again."
Another passage again proclaims asat (non-existence) as the original cause in
the following words:
asad evedam agra āsīt tat samabhavat
"In the beginning was non-existence. From non-existence this world was
manifested."
Another passage (Chāndogya Upaniṣād 6.2.1) proclaims Brahman the original
cause in the following words:
sad eva saumyedam agra āsīt
