śharīraṁ yad avāpnoti yach chāpy utkrāmatīśhvaraḥ
gṛihītvaitāni sanyāti vāyur gandhān ivāśhayāt|| 8 ||

My Understanding : The soul is Eeswara. When the body dies, the soul moves on to another body. The soul experiences the joys, sorrows, sensations, and mental states of the body it inhabits. As the soul transfers from one body to the next, it carries with it the experiences and impressions from the previous life, continuing the cycle of happiness, sorrow, and perception.
