Ethics is knowing the difference between what you have a right to do and what is right to do.
Ethics or simple honesty is the building blocks upon which our whole society is based, and business is a part of our society, and it's integral to the practice of being able to conduct business, that you have a set of honest standards.
Ahimsa -- Non-violence. Not harming other people or other sentient beings. Not harming onesself. Not harming the environment. Tolerance even for that which we dislike. Not speaking that which, even though truthful, would injure others.
Satya -- Truthfulness. Note that sometimes we may know our words are literally true, but do not convey what we know to be truthful. This is a child's game. Satya means not intending to deceive others in our thoughts, as well as our words and actions.
Asteya -- Non-stealing. Not taking that which is not given.
Brahmacarya -- Sexual responsibility. Regarding others as human beings rather than as male and female bodies. The spirit of this precept is conservation of energy for the purpose of spiritual practice. This includes not only sexual restraint, but protecting our energy for instance by avoiding endless chattering with no clear purpose.
Aparigraha -- Abstention from greed. Not coveting that which is not ours. Avoidance of unnecessary acquisition of objects not essential to maintaining life or spiritual study.
Leadership is about raising the aspirations of followers and enthusing people with a desire to reach for the stars. For instance, Mahatma Gandhi created a vision for independence in India and raised the aspirations of our people.
Leadership is about making people say, 'I will walk on water for you.' It is about creating a worthy dream and helping people achieve it.
Robert Kennedy, summed up leadership best when he said, 'Others see things as they are and wonder why; I see them as they are not and say why not?'
It is perfectly all right to ask if there is a reward for being good, but this has nothing to do with whether one should be good. It makes no sense to try convince people that they should be good by pointing to the rewards that may follow. One should be good because “good” is, by definition, that which one should be.
As for motivation, good behavior often brings a reward, but not every time. Think about it. If it were always in one’s interest to be good, there would be no need for ethics. We could simply act selfishly and forget about obligation. People invented ethics precisely because it does not always coincide with self interest.
A man does what he must.. in spite of personal consequences, in spite of obstacles and dangers, and pressures.. and that is the basis of all human morality.
