Legend has it that Ganapathy himself wrote the Mahabharata, to the dictation of Guru Veda Vyasa. He is also considered the most intelligent. A challenge was thrown to brothers Ganapathy and Karthikeya by Sage Narada. The challenge was whoever went around the globe first would have the fruit first. Karthikeya went around the world which took quite some time while Ganapathy went round his parents thrice and claimed the fruit. The logic he gave was that since his parents represented the universe he had gone round them.
Now do not look at this story as a rational logical person but try and understand the thought behind it. It is to do with the use of the Intellect. Ganapathy used it to know what the Sage meant while his brother took the Sage ka order at face value. Similarly in our lives we must learn to use our Intellect (the ability to discriminate between right and wrong) and look at the deeper meanings of things. Using our intellect will force us to make decisions, right or wrong, time will tell. If wrong, so what, we will learn by our mistakes. The key is to try.
