This quote essentially means that any teaching or doctrine that is in stark contradiction with universally accepted truths and morals cannot hold its ground. The term “Shastra” refers to a category of foundational texts of knowledge in Indian traditions, often serving as guides in various fields like law, arts, ethics, etc. However, Gandhi suggests that even these revered texts cannot be considered infallible if they contradict universal truths and morals.

In essence, Gandhi emphasizes the importance of critical thinking and the necessity to question even the most established and respected sources of knowledge. He encourages us to not blindly accept any information or teachings, but to weigh them against universal truths and moral principles.

Applying this in today’s world, we can see that this idea is particularly relevant in the era of information overload. With the internet, we have access to vast amounts of information, and not all of it is accurate or ethical. It’s essential to critically evaluate the information we consume, question its source, and measure it against universally accepted truths and morals.

In terms of personal development, this quote can be interpreted as a call to cultivate discernment and critical thinking skills. It encourages individuals to develop their own moral compass and not just accept doctrines or beliefs because they are widely accepted or have been around for a long time. It’s about learning to think for oneself, to question, and to seek truth, which are crucial aspects of personal growth and self-development.
