The story of Gandhiji’s three monkeys is very popular. The will to evil is predominant in human beings. So Gandhiji came up with:
See no evil, Speak no evil, Hear no evil.
The well-known picture of the three monkeys depicts the same so vividly. Just like following these three cardinal principles can make life beautiful, there are three impulses to avoid to make life beautiful. Gandhiji’s cardinal principles were to beat addiction to evil, these three principles are to beat unnecessary addiction to action.
