Regarding your questions about pujari, pujari means who will always be with the Deities. That is pujari. So far as the difficulty with bathing, you can heat up some water in the morning and wash yourself over with a sponge or a cloth.* That will be all right if there is no hot water for regular showers.
Please offer my blessings to the others. I hope this will meet you in good health.
Your ever well-wisher,
A.C. Bhaktivedanta Swami
*In special cases you can simply wash your hands and feet and change your dress washed. That will purify you.
