5.15, Sloka 15, Chapter 5:
Lord Krishna reaffirms that he is not touched by the sins of the people and also the virtues of people. The actions of the people remain in the material world and people are responsible for their actions.
This Sloka explains why people perform sins or actions that bind them to the material world. The reason is simple. As long as the person is ignorant or doesn’t know what the truth is, he will be committing actions that bind him to actions.
The purpose of human beings is to endeavor to clear the veil of ignorance. Ignorance covers knowledge like ash covers the fire. We should clear the ignorance first, gain knowledge and work for the betterment of humanity.
5.16, Sloka 16, Chapter 5:
In this sloka, Lord Krishna gives assurance that ignorance can be removed. Some people remove the ignorance through constant practice. Knowledge is like a sun illuminating the whole space of ignorance. If ignorance is darkness, then knowledge is the light that we can use to come out of the darkness. That’s why a lot of emphases is placed on educational institutions, which transfer the knowledge and remove the ignorance of people.
We should read subject philosophy to gain more knowledge about various thought process scholars has about human beings. Also, knowledge can be self-taught through rigorous inquiry and be searching for answers as to what exactly is the truth.
