Supreme Soul (CC and Other Books)

CC Adi 2.37, Purport:
As the vast earth is the source for the ingredients of all earthen pots, so the Supreme Soul is the source for the complete substance of all individual living entities. The cause of all causes, the Supreme Personality of Godhead, is the cause of the living entities. This is confirmed in the Bhagavad-gītā (7.10), where the Lord says, bījaṁ māṁ sarva-bhūtānām ("I am the seed of all living entities"), and in the Upaniṣads (Kaṭha Up. 2.2.13), which say, nityo nityānāṁ cetanaś cetanānām ("the Lord is the supreme leader among all the eternal living beings").
