Hello arjun,
yes, I have one too. A first day cover in fact. I always wondered why it was not Shiva, or the Trimurti as you say. Then at least there is some connection to god for people. Although I do kind of understand why the Seniors push Brahma Baba - they adored him so. No doubt this is why they made the stamp but Brahma Baba never wanted it. He did not even want his picture taken. I remember we were also discouraged from taking snaps in the early days too. Anyway ... drama you could say. All things are good. It is hard for them (Seniors) I think to separate loving Brahma a lot, promoting Brahma and promoting the organisation. To me they are all quite distinct, but I think many see them as one and the same.
I remember telling an Indian Sister one time that I wanted to teach people meditation but not promote the BKWSU. And she was astounded, saying that it is the same thing. I lived in India some time back and they do not separate things in the way that we do. I am a Videshi Bhai and maybe you are an Indian Bhai, so you would have that culture anyway. But for us from 'industrialised' nations, we are used to clear distinctions. It must have been very interesting to have lived through that time in the 1930's with so much love and belonging for people, even if The Knowledge was not clear, it did not seem to matter for people because of the love and the peace.
Oh, I think I rambled on a bit. But anyway. I will not have the computer soon so I should make the most of it and post while i can.
Om Shanti,
chai Bhai
