So far your question is concerned, should the Jagannatha deity be bathed with water, that is not necessary. They should be washed once in a year, that is sufficient, 15 days before Rathayatra. That is called "sananyatra" ceremony. Otherwise if you bathe, that will damage the wood.
Regarding general state of affairs at Amsterdam temple, I can understand there is some disturbance among you, but that is not to be taken very seriously. Real business is preaching work, and if there is full attention on this matter only, all other businesses will be automatically successful. Fighting amongst ourselves is not at all good, but if our preaching work is neglected, or if we fall down in following the regulative principles such as rising before four, chanting 16 rounds, like that, if these things are not strictly observed then maya will enter and spoil everything. So my best advice to you is to strictly observe these things yourself and be the example so that all others may follow. We should not criticize each other, as Vaisnavas, because there is fault in everyone and we may be ourselves subject to criticism. Best thing is to be above suspicion ourselves, then if we see discrepancies and make suggestion the others will automatically respect and take action to rectify the matters. That is cooperation. And we must exist on such cooperation, otherwise the whole thing is doomed if we simply go on fighting over some small thing. So try to organize things and preach together in this spirit, and that will please me very, very much.
