punara vartino ajuna
mam upetya tu kauntey
punara janm na vidhyate" (Bhagwat Gita: Chapter VIII verse 16)
"From the highest planet of Brahm Loka in the material world down to the lowest world, all are places of misery wherein a person's Soul (Jeeva) comes in repeated birth and death from time to time. But one who attains to to Me (God), O Arjuna, never takes birth again."
We all know that this body of ours shall perish or die in future & our soul shall leave this body apartment. But as per 'Bhagwat Gita', we in essence are different than this body & we in essence are that indestructible 'Soul. This 'Soul' is there in our body, different than the body, even when we are living right now. As per 'Bhagwat Gita -Chapter Two Verse - 22', our body is like our clothes that we wear on our body & after death these worn out clothes are dropped by the embodied soul . You in essence are a 'Soul' & this 'Soul' of yours shall wear another body (read, shall wear another pair of clothes) after death. So this eternal Soul which is indestructible, changes its present embodied form for another embodied form, when the physical body perishes.
So, your soul which is living in this body temple, shall leave it when this body shall be worn out. Till then you shall have to give it food etc. as rent & the day you stop giving it rent of food, air etc. you shall have to leave this body. Otherwise also the actual houses or homes of yours in which you live at present are all part & parcel of God's creation & you need to vacate this at death. So let's always remember that we all are living temporarily on this earth for a short period & one day we shall have to go leaving all this. So let's not get attached much to our relations & property etc. & devote more time in the service of God.
