Srimad Bhagavatam Canto 11, Chapter 22, Text 14

SB 11.22.14

purusah prakrtir vyaktam
 ahankaro nabho ’nilah
jyotir apah ksitir iti
 tattvany uktani me nava
 
Translation: 
 
I have described the nine basic elements as the enjoying soul, nature, nature’s primeval manifestation of the mahat-tattva, false ego, ether, air, fire, water and earth.
 
Purport: 
 
Prakrti, or nature, is originally unmanifest and later becomes manifest as the mahat-tattva. Although the living entity is purusa, an enjoyer, the real process by which he can enjoy is by satisfying the transcendental senses of the Lord, just as the hand eats by supplying food to the stomach. Within material nature the living entity becomes a false enjoyer, forgetting his subservience to the Lord. The material elements as well as the living entity and the Supersoul are thus systematically analyzed to demonstrate to the conditioned soul his actual constitutional position beyond material nature.
