I am open to spread of your religion however since Hinduism doesnt allow conversions and i understand since it has different classes (low cast/ high cast) you may call these different philosophies but again the question is if someone converts to Hinduism how will you classify him? Dalit or Brahmin?
Apart from that can you tell me who can become a Pundit ?
Let me put in very straight way:
1. There is no conversion procedure in Hinduism, you would automatically convert to Hinduism when u start understanding n believing in Hinduism in true sense.
2. If somebody converts to Hinduism at max u can determine his Varna i.e. the broader distinction based on the type of work u do like if somebody is in Army he can call himself a Kshatriya n ''may'' take Arjun as his idol for performing his duties, if ur a Scholar, lecturar or Scientist u may call ur self a Brahmin, etc etc..
3. Besides the caste system(like Baniya, Sunar, Rajput,etc.) is applicable only for those who r Hindus by birth n there lineage can be determined through their ''Gotra''.
4. There is no hard n fast rule here there r example through out our history were many people have converted from one Varna to another like Brahma Rishi Vishvamitra was originally a Kshatriya a very brave warrior who later converted not only to Brahmin but even achieved its greatest highest by earning the title of Brahma Rishi though his penence or we have the example of Lord Parshurama(An Avatar of Lord Vishnu) who was a mixture of Brahmin n Kshatriya,etc...
5. Pundit n Brahmin r two different things, a Pundit is one who has knowledge of Vedic n Spiritual text n could perform Puja n Havan which normal people can't due to lack of knowledge about the correct mantras, etc..
A Brahman is a much wider term n a Pundit is included in it.
