The Sanskrit corresponding to "Nanwu" should actually be namo, not namas. (namas is a singular nominative form), because Sanskrit has the rule of tone sandhi. When namas is put in a sentence, as will become H. If there is a specific consonant prefix after aH, aH will be converted into O, which is "namo".

Namo is written as a celestial body:? .

Bai Lianhua's Sanskrit is puNDarika.

As for tattoos, I agree with Yu Yu very much. Better not. You can put a stamp on it, and then you can buy books and write letters yourself. How nice it is to put stamps on it. Or make a pendant with this pattern. It's very cool. In particular, the lotus pattern is very suitable for making pendants and bracelets. Tattooing your body is not only disrespectful to your parents, but also disrespectful to religion.
