4. One asura Trinavarta whirlwind took Baby Krishna into the sky and was fighting with Him. The idea was to take Krishna into the sky and drop Him. But once in the sky, Krishna fought with the whirlwind, and the demon fell down dead while Krishna was lying happily on the ground. Yasoda was praying in thanks that "God has saved my Boy."
Regarding your question about placing an effulgence around Krishna's head in all of these pictures, yes this should be done. I hope to be receiving the previous paintings you have done soon. Kindly convey my blessings to all others at Boston temple.
