Power can be self-destructive. Hence, with great power comes a great responsibility.
For an elephant, the trunk is the most important part of his body. It enables the animal to pick up food, collect water, breathe and also communicate with each other.
The elephant, when angry, also uses its trunk to punish miscreants.
If you observe the trunk of Ganesha on any idol, it is always rolled up in a certain fashion. This suggests that he controls the power he wields.
While it is important to possess power, which can come from wealth, intelligence or one’s success, it is equally pertinent to have control over it.
