sattvam rajas tama iti

nibadhnanti maha-baho
dehe dehinam avyayam

"Material nature consists of three modes—goodness, passion and ignorance. When the eternal living entity comes in contact with nature, O mighty-armed Arjuna, he becomes conditioned by these modes."

Nibadhnanti = is bonded. Avyayam = birthless in the natural state or without the three qualities in the natural state, dehinam = Atman, dehe = in the body, nibadhnanti = bonded. In its natural state Atman has no births or deaths, nor is associated with sattva, rajas and tamas qualities; yet, Atman is bonded in a body by these qualities in samsara.Where are those Three qualities? Are they stuck with Atman or with the body? Could we see them? Unless we know their place of origin, how can we destroy them? Iti = these, sattvam, rajas, tama = sattva, rajas and tamas, gunah = qualities, prakruti-sambhava= always associated with Prakriti. They are an integral part of Prakriti, which transforms into a body. Therefore, these Three qualities are inseparable from our bodies. Now we will see the replies for the questions raised. Karma gives rise to birth in a body; so after birth that karma is spent and is over. After birth, having spent karma, Atman should be in its natural state. Why it is not so? Because, birth is in a body, which has the Three qualities as an integral part. Therefore, Atman is influenced by the body and the Three qualities, and so Atman desires to experience pleasures and pains. The desire impels to do various actions. These actions are responsible for the consequent Punya/Papa. These induce rebirths on and on. Thus the integral sattva, rajas and tamas qualities of Prakriti, are in the body and cause further Papa/Punya. Prakriti is the basic raw material and its qualities are seen in the body. It is like, for example, if we make a pot out of the clay of particular colour, the same colour is seen in the pot. The colour of the thread is reflected in the cloth and garments. We should remember Prakriti is not these Three qualities, but Prakriti's nature. The five perceptions like the taste, smell, etc. are also qualities of Prakriti, but of temporary nature. Whereas sattva, rajas and tamas are permanently in Prakriti and can never be separated. Though these three qualities can never be seen, their effects can be felt. If sattva is predominant at any time, the person would be very bright; rajas would make him increase desire. Like poison's nature of killing is not visible, here also effects only will reveal the presence of these three qualities. Thus the inseparable three qualities in the body, induce one to act and acquire Papa/Punya and consequent births. The Lord is going to explain further each quality. Swami Doodayacharya breathed his last in Srimushnam, on Aippasi -Ashtami, in 1607.
