Srimad Bhagavatam Canto 11, Chapter 22, Text 12

SB 11.22.12

prakrtir guna-samyam vai
 prakrter natmano gunah
sattvam rajas tama iti
 sthity-utpatty-anta-hetavah
 
Translation: 
 
Nature exists originally as the equilibrium of the three material modes, which pertain only to nature, not to the transcendental spirit soul. These modes — goodness, passion and ignorance — are the effective causes of the creation, maintenance and destruction of this universe.
 
Purport: 
 
In Bhagavad-gita (3.27) it is stated:
 
prakrteh kriyamanani
 gunaih karmani sarvasah
ahankara-vimudhatma
 kartaham iti manyate
 
“The bewildered spirit soul, under the influence of the three modes of material nature, thinks himself to be the doer of activities, which are in actuality carried out by nature.”
 
The three modes of nature, in their original state of equilibrium, as well as the subsequent creation generated from the modes, are vastly more powerful than the tiny living entity who is controlled by them. The living entity thus cannot be accepted as the actual doer or creator within the material world. The mode of goodness is symptomized by the experience of knowledge, the mode of passion by the experience of work, and the mode of ignorance by the experience of darkness. These modes of material knowledge, work and darkness have no real relation with the transcendental spirit soul, who exhibits his own qualities of eternality, bliss and knowledge (the sandhini, samvit and hladini potencies of the Supreme Lord). The material modes have no access within the kingdom of God, in the unbounded atmosphere of which the eternal living entity is meant to live.
