bhartuḥ sa me syād yadi vīra bhāraḥ
gantur yadi syād adhigamyam adhvā
pīveti rāśau na vidāṁ pravādaḥ
In Bhagavad-gītā 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. Jaḍa 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.
