Śrīla Bhakti Vinod Ṭhākur vividly illustrates the delusion of attachment to the material body.
The following song is from Śrī Kalyāṇa-kalpa-taru (1.11).
O brother! Why are you proud of your body? The body is temporary. It never lasts forever. When Death arrives, the body is nothing. It becomes cold, its eyes become motionless, and it is reduced to ashes in a funeral pyre.
This body, whose face and beauty you constantly look at in the mirror, will become food for dogs and jackals. Where will you keep the garments you adorn this body with and the ornaments you decorate it with then?
Your wife, children, and friends will take you to the crematorium, burn you, and then return home. To whom do you belong? Who belongs to you? Now understand this and see the truth. The body will certainly be destroyed.
You should desire true, eternal fortune, constantly sing the Lord’s glories, and always chant the Lord’s Name. O mind! Give up your misconceptions and worship Kṛṣṇa. He is Vinod’s sole shelter.

“‘If those whom the Lord blesses take shelter of His feet in all respects without duplicity, then they transcend the Lord’s insurmountable māyā. Such souls have no conception of a jackal or dog’s food (the body) to be ‘me’ or ‘mine’.
