The only answer to this is that there is someone besides this body, in the body, which makes it so lovable, otherwise how it is that this body of five nature elements seems so attractive & lovable. Yes, there is some other thing in this body which makes it so lovable & that thing is divine Soul. This divine Soul is nothing but a spark of universal omnipresent Soul, the Almighty God. All human beings are lovable due to the presence of this divine Soul in the body. All attractions in the body are due to this divine Soul only. Once this divine Soul leaves this body, it is called death of that body & all attractions, all love departs with the Soul.
God himself says in the Bhagwat Gita that He Himself resides in the heart of all human beings. Below verse explains that:
hrd-dese ’rjuna tishthati
yantrarudhani mayaya" (Bhagwat Gita: Chapter Eighteen verse 61)
"Sri Krishna said: O Arjuna, The Lord / Supreme God dwells in the heart of all beings, who are mounted on the automation of this body, causing them by His illusive power of material energy to revolve (according to their actions) and is directing the wanderings of all living entities."
"tam eva saranam gaccha
tat-prasadat param shantim
sthanam prapsyasi sasvatam" (Bhagwat Gita: Chapter Eighteen verse 62)
"Sri Krishna said: O Arjuna, surrender unto God fully. By His grace you will attain transcendental peace and the supreme and eternal abode."
Jai Shri Krishna
