What do we need to do to protect ourselves and be of utility to those around us?

Destroy all your evil qualities such as pride, ego and wickedness. Whenever you drive away all these evil qualities, you will become a pure human being. Wherefrom does humanness come? It comes from your heart. Here, the heart is not referred to as the physical heart but the spiritual heart, which is free of all blemishes. Like fragrant air, your purity should spread everywhere. You should share with others, pure thoughts and pure feelings that emanate from you. Whatever you do, it should be helpful to others.
