Today is Ganesh Chaturthi - the birthday of the Hindu God, Ganesha.
"Ganesha is the power of knowledge, success and fulfillment. It is believed that mantras of Ganesha, when chanted with genuine devotion, give positive results."
I've picked one of his mantras for today's Peace Thimble, from iloveindia.com:
Aum Lambodaraya Namah
"This means you feel that you are the universe ... Like an entire tree is in the seed, the whole universe is in the sound of creation, which is Aum ...
Therefore, if you say, realizing the oneness with the universe, "shanti to the world" every day, then the grace of God will come and there will be world peace, universal peace."
