The word guṇa-vyatyaya-jaḥ is significant in this verse. Vyatyaya indicates change or inversion in the normal order of things. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura has described the concept of vyatyaya by giving the Sanskrit synonym vaiṣamya, which indicates inequality or disproportionate diversity. Thus, it is understood by the term guṇa-vyatyaya-jaḥ that the body is generated by the unstable relationships of the three modes of material nature, which exist everywhere in constantly changing proportions. There is constant strife among the modes of nature. A good person is sometimes torn by passion, and a passionate person sometimes wants to give up everything and rest. An ignorant person may sometimes become disgusted with his depraved life, and a passionate person may sometimes indulge in bad habits in the mode of ignorance. Due to the interactive conflict of the modes of nature, one wanders throughout material nature creating one body after another by one’s own work, karma. As it is said, variety is the mother of enjoyment, and the variety of material modes gives hope to the conditioned souls that by changing their material situation their unhappiness and frustration can be turned into happiness and satisfaction. But even if one acquires relative material happiness, that will soon be disturbed by the inevitable flux of the material modes.
