Namaste All,

I'm no authority on japa, but from my personal experience I think that one should not be worried about chanting Shiva's name on Tulsi mala or chanting Krishna's name on Rudraksha mala. Especially if you are not in a position to buy two different malas for two different names. I used to chant HK maha mantra on my tulsi mala, but since few days ago I started chanting Shiva's name on same mala, and it's still very powerful indeed. After chanting I put it around my neck and start meditating. Since vibration of Shiva's name stays within mala after chanting, it really helps to put me in deep meditative state. I sincerely suggest others to do the same and see how it effects you.

And I agree on not wearing malas around neck everyday, since they're not jewelry, but your own tool for spending some intimate time with God.

Blessings.
