"And why the elephant head? The principle qualities of the elephant are wisdom and effortlessness. The enormous head of the elephant signifies Wisdom and Knowledge. Elephants don't walk around obstacles, neither are they stopped by them. They just remove them and walk ahead – signifying effortlessness. So, when we worship Lord Ganesha these elephant qualities within us are kindled and we take on these qualities." ~ The Art of Living
