Samaparn,
please DO NOT include a business card or mention that you're a professional performer, or remotely mentioning that you intend to perform in the US. You might end up missing your flight, as long as you can't produce a working visa.
American folks - please correct me if I'm wrong on this one...
Simply declare the toys as "sports equipment", "toys" whatsoever. Do not burn them within 24hrs prior to departure, make sure they are dry and not smelling.
Be prepared to leave them behind without making *any* fuzz.
Airport staff is empowered to keep you grounded, if they have reasons to believe that you might become a threat to the safety of other passengers (a few years ago, when I was insistingly complaining about my reservation, I stayed grounded and had to wait for the next flight.... hang on, maybe that's a good way of getting your toys back home...? as long as you got no schedule to follow).
Apart from all that: best of luck, safe travels and enjoy the Ashram.
PS: let us know how it went - always good to know the latest in airtravel regulations
