No tasleemat is also a poetic way of saying salam.You can't just make up stuff, Tasleem means acceptance.
Change it to Tasleem Mataram then
Or wait wait, I can do Hindi too: Sweekaar Mataram? Or can you make it like Sweekar Bharatum? Perfect hojaye ga.
See we can all make up stuff.
Ever heard of the greetings during sher shayar sessions?
Yaarane Bazm, Aadab o tasleemat !
I do know a little bit Urdu as well you know
