Regarding the worship of our Gaura Nitai by women pujaris, we worship Lord Caitanya in His householder life when He was with His wife, and not as a sannyasi. So, it is alright for women to do this service. But, besides this, service is spiritual and there can be no material designation. In Bhagavad-gita it is stated by Lord Krishna: striyo vaisyas tatha sudras te'pi yanti param gatim. The principle is that everyone who is properly initiated and following the rules and regulations can worship. This activity can not on the material platform.
