Contemplans, you might find this very interesting:
Here is a quote from it (but there is much more to see):
The Buddha has enumerated the qualities that should be present in a good nurse. He should be competent to administer the medicine, he should know what is agreeable to the patient and what is not. He should keep away what is disagreeable and give only what is agreeable to the patient. He should be benevolent and kind-hearted, he should perform his duties out of a sense of service and not just for the sake of remuneration (mettacitto gilanam upatthati no amisantaro). He should not feel repulsion towards saliva, phlegm, urine, stools, sores, etc. He should be capable of exhorting and stimulating the patient with noble ideas, with Dhamma talk (A.iii,144).
Caring for others - and yes that includes the bodies of others - is important
on the Buddhist Path.
Regarding the idea that this body is a 'vehicle': this is leaning more towards Hinduism, who hold that there is a transmigrating 'soul or self' discarding old bodies, and accepting new ones (like clothing). As far as I know, this is not
the right way to look at it, from a Buddhist perspective. But the Doctrine of the self-less-ness of the five khandhas is not easy to grasp without meditation; I heard Ajahn Chah say that 'if you only intellectualize about it, your head will explode'. So we can talk about it until we are all blue in the face, but you will be no closer to seeing it unless you contemplate it with a calmed mind. Personally, it took me years to stop being averse
to it; then I began to investigate
it, intellectually and via meditation, and this is an ongoing process. But as you will see above if you click on the link, the fact that the body also
isn't self (along with feeling, perception, etc), in no way releases us from our duty to care for other beings. When we see suffering, we should act to relieve it whenever possible.
