SB 4.29.26-27

yadatmanam avijñaya
 bhagavantam param gurum
purusas tu visajjeta
 gunesu prakrteh sva-drk
gunabhimani sa tada
 karmani kurute ’vasah
suklam krsnam lohitam va
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
The living entity by nature has minute independence to choose his own good or bad fortune, but when he forgets his supreme master, the Personality of Godhead, he gives himself up unto the modes of material nature. Being influenced by the modes of material nature, he identifies himself with the body and, for the interest of the body, becomes attached to various activities. Sometimes he is under the influence of the mode of ignorance, sometimes the mode of passion and sometimes the mode of goodness. The living entity thus gets different types of bodies under the modes of material nature.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
These different types of bodies are explained in Bhagavad-gita (13.22):
purusah prakrti-stho hi
 bhunkte prakrtijan gunan
karanam guna-sango ’sya
“The living entity in material nature follows the ways of life, enjoying the three modes of nature. This is due to his association with that material nature. Thus he meets with good and evil among various species.”
Because of associating with the modes of nature, the living entity gets a variety of bodies from the 8,400,000 forms. It is clearly explained herein that the living entity has a little independence, indicated by the word sva-drk, meaning “one who can see his own welfare.” The living entity’s constitutional position is very minute, and he can be misled in his choice. He may choose to imitate the Supreme Personality of Godhead. A servant may desire to start his own business and imitate his master, and when he chooses to do so, he may leave the protection of his master. Sometimes he is a failure, and sometimes he is successful. Similarly, the living entity, part and parcel of Krsna, starts his own business to compete with the Lord. There are many competitors out to attain the Lord’s position, but to become like the Lord is not at all possible. Thus there is a great struggle for existence with the material world as different parties try to imitate the Lord. Material bondage is caused by deviation from the service of the Lord and attempts to imitate Him. The Lord is imitated by Mayavadi philosophers, who try to become one with the Lord in an artificial way. When the Mayavadi philosophers think of themselves as liberated, they are under the delusion of mental concoction. No one can become one with or equal to God. To imagine this is to continue one’s bondage in material existence.
