Srimad Bhagavatam Canto 05, Chapter 10, Text 09

SB 5.10.9

brahmana uvaca
tvayoditam vyaktam avipralabdham
 bhartuh sa me syad yadi vira bharah
gantur yadi syad adhigamyam adhva
 piveti rasau na vidam pravadah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The great brahmana Jada Bharata said: My dear King and hero, whatever you have spoken sarcastically is certainly true. Actually these are not simply words of chastisement, for the body is the carrier. The load carried by the body does not belong to me, for I am the spirit soul. There is no contradiction in your statements because I am different from the body. I am not the carrier of the palanquin; the body is the carrier. Certainly, as you have hinted, I have not labored carrying the palanquin, for I am detached from the body. You have said that I am not stout and strong, and these words are befitting a person who does not know the distinction between the body and the soul. The body may be fat or thin, but no learned man would say such things of the spirit soul. As far as the spirit soul is concerned, I am neither fat nor skinny; therefore you are correct when you say that I am not very stout. Also, if the object of this journey and the path leading there were mine, there would be many troubles for me, but because they relate not to me but to my body, there is no trouble at all.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In Bhagavad-gita it is stated that one who is advanced in spiritual knowledge is not disturbed by the pains and pleasures of the material body. The material body is completely separate from the spirit soul, and the pains and pleasures of the body are superfluous. The practice of austerity and penance is meant for understanding the distinction between the body and the soul and how the soul can be unaffected by the pleasures and pains of the body. Jada Bharata was actually situated on the platform of self-realization. He was completely aloof from the bodily conception; therefore he immediately took this position and convinced the King that whatever contradictory things the King had said about his body did not actually apply to him as a spirit soul.
