Srimad Bhagavatam Canto 05, Chapter 10, Text 10

SB 5.10.10

sthaulyam karsyam vyadhaya adhayas ca
 ksut trd bhayam kalir iccha jara ca
nidra ratir manyur aham madah suco
 dehena jatasya hi me na santi
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Fatness, thinness, bodily and mental distress, thirst, hunger, fear, disagreement, desires for material happiness, old age, sleep, attachment for material possessions, anger, lamentation, illusion and identification of the body with the self are all transformations of the material covering of the spirit soul. A person absorbed in the material bodily conception is affected by these things, but I am free from all bodily conceptions. Consequently I am neither fat nor skinny nor anything else you have mentioned.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Srila Narottama dasa Thakura has sung: deha-smrti nahi yara, samsara-bandhana kahan tara. One who is spiritually advanced has no connection with the body or with the bodily actions and reactions. When one comes to understand that he is not the body and therefore is neither fat nor skinny, one attains the topmost form of spiritual realization. When one is not spiritually realized, the bodily conception entangles one in the material world. At the present moment all human society is laboring under the bodily conception; therefore in the sastras people in this age are referred to as dvipada-pasu, two-legged animals. No one can be happy in a civilization conducted by such animals. Our Krsna consciousness movement is trying to raise fallen human society to the status of spiritual understanding. It is not possible for everyone to become immediately self-realized like Jada Bharata. However, as stated in Srimad-Bhagavatam (1.2.18): nasta-prayesv abhadresu nityam bhagavata-sevaya. By spreading the Bhagavata principles, we can raise human society to the platform of perfection. When one is not affected by the bodily conceptions, one can advance to the Lord’s devotional service.
nasta-prayesv abhadresu
 nityam bhagavata-sevaya
bhagavaty uttamasloke
 bhaktir bhavati naisthiki
The more we advance our freedom from the bodily conception, the more we are fixed in devotional service, and the more we are happy and peaceful. In this regard, Srila Madhvacarya says that those who are too materially affected continue the bodily conception. Such persons are concerned with different bodily symptoms, whereas one freed from bodily conceptions lives without the body even in the material condition.
