This quote is a profound statement on the nature of principles, morality, and goodness. It asserts that a principle, to be truly worthy of being called a principle, must be wholly good. This means that it must be universally beneficial, morally upright, and ethically sound. It should not contain elements of harm, deceit, or inequality. If a principle is not wholly good, then according to Gandhi, it loses its essence and value and is not worthy of being followed or respected.

In essence, this quote is a call for uncompromising integrity and moral consistency. It’s a reminder that we should not settle for principles that are only partially good or beneficial. Instead, we should strive for those that reflect the highest standards of goodness and righteousness.

Applying this idea to today’s world, one could argue that it underscores the importance of ethical leadership and governance. In a society, the principles that guide our leaders and institutions should be wholly good. They should promote fairness, justice, and the common good, rather than serving narrow interests or promoting inequality.

In the realm of personal development, this quote can serve as a moral compass. It encourages us to adopt and live by principles that are wholly good. This could mean standing up for what is right, even when it is difficult; treating others with kindness and respect, even when they do not reciprocate; or striving for honesty and integrity, even when deception might be easier or more beneficial in the short term.

In conclusion, this quote serves as a call to action for each of us to examine the principles that guide our lives and to ensure that they are truly good in every sense of the word. It’s a reminder that in the pursuit of personal growth or societal progress, the ends do not justify the means. Instead, the means themselves must be just, ethical, and good.
