To Play the bowl with The Wooden Mallet (or Pudja) , place your bowl on your non-dominate open palm, keep your hand as open and flat as possible to let the bowl resonate at it's full potential. Hold the wooden mallet in your dominate hand, Keeping your grip toward the center of the mallet so you have good leverage. It's not important how you hold the mallet, as long you have it up and at a slight angle, and it's comfortable enough to press firmly on the bowl. ( I like to hold my mallet like a pencil.) Now rub the mallet on the outer part of the rim, in a circular motion making sure you keep consistent contact with the bowl. As the bowl begins to sing try and press a little harder and play a little slower each time around, as to trap the sound so it doesn't chatter. The key is to play the bowl slow with pressure, try not to speed up. When it plays at a comfortable tone release the mallet quickly and away from your body.
  Here's A Little Trick: After Your bowl has begun to sing, face your bowl, and tilting your head slightly, and close enough to kiss it, open and close your mouth as if to say “Wow”. The sound waves will resonate in your mouth and your mouth will become a sound chamber. The “Wah-Wah” sound is fun to do and you can get a different sound effect from the bowl.
  Striking The Bowl: Holding your bowl again in your non-dominate open palmed hand. Strike the bowl either with a striker or the heel of your dominate hand, get close to the bowl and you'll hear yet another tone. Usually a bit deeper and very “Ohm” like sound. Which gives most people a very relaxing sensation.

  To Play The Bell:  Hold stem of the bell in your non-dominate hand firmly.  Holding your wooden mallet in the opposite hand, pointed towards the ceiling, rub the outside edge of the bottom rim of the bell in a circular motion with consistant pressure until it resonates at a nice volume.  (The dorje does not make any sound.)
