The Three Gunas Give Impetus to Karma - 18-40

1 Gita Sloka  Every Day - Chapter 18 - Moksha Sanyasa Yoga - Sloka 40

Na tat asti prithivyam va divi deveshu va punah I

Sattvam prakriti jaih muktam yat ebhih asyat tribhih gunaih II sloka 40

न तत् अस्ति पृथिव्यं व दिवि देवेषु व पुनः I 
सत्त्वं प्रकृति जैः मुक्तं यत् एभिः अस्यत त्रिभिः गुणैः II श्लोक 40

There is no being on earth, or again in heaven among the devas, that is liberated from the three gunas, born of prakriti.

The three gunas and prakriti are identical. The former are taken into account when distinction is to be made among the attainments of the jivatmans. But as the aggregate substance, the gunas and prakriti are one and the same. From the blade of grass up to Brahma the creator, all the jivas are bound by the gunas of prakriti. Whether they be the celestial beings or humans, they are all in bondage until they transcend the three gunas. The continuity of births and deaths is inevitable to them when they are in the fetters of prakriti. Their rebirths range high and low conforming to the predominance in them of the varying gunas. Brahma the creator is the foremost among the jivatmans. His functional status is the greatest; but he is not a liberated soul. In other words, he is also involved in the gunas. 

Hence there is no being which is free from the three gunas of prakriti, whether men or devas or other beings on earth or heaven - from Brahma down to the smallest immovable object
