In the beginning, all this was Pure Being, One without a second.
It thought: 'May I be many, may I grow forth.' It projected fire.
The fire thought: 'May I be many, may I grow forth.' It projected water.
Therefore, whenever anybody is hot, he perspires and water is produced on him from fire alone.
The water willed: 'May I be many, may I grow forth.' It projected food.
Therefore, whenever it rains anywhere, food is then produced. From water alone eatable food is produced.
The being thought: 'Well, may I enter into all these three things with this living self (Jivatma). Let me appear under different names and forms.'
