Regarding whether the Brahmajoti should be painted rainbow colored. It is our experience that in the material world when the sunshine is very bright there is not any color, just whiteness. Colors of sunshine only become manifest when there is a tinge of clouds. So in the Brahmajoti there is no possibility of material tinge. So how it can be rainbow colored? In the dazzling light there is no possibility of colors. Considering all these points, Muralidhara should paint maintaining the artistic sense as well.
The Mahattattva may be shown underneath the lotus if it is required for design purposes.
In reply to Jayadvaita's questions, henceforward the policy for using diacritic markings is that I want them used everywhere, on large books, small books and also BTG. If there is any difficulty with the pronunciation, then after the correct diacritic spelling, in brackets the words "pronounced as _", may be written. So even on covers the diacritic markings should be used. We should not have to reduce our standard on account of the ignorant masses. Diacritic spelling is accepted internationally, and no learned person will even care to read our books unless this system is maintained.
