You can tell a lot about someone by the things and people they surround themselves with. On the one hand, this is because where we choose to put time and effort is a reflection of what we value. On the other hand, it is also because we are shaped by our environments: we become like what we are surrounded by. This statement is true spiritually. If we surround ourselves with heavenly influences, we will become heavenly. If we surround ourselves with hellish influences, we will become hellish. Where and how we spend our time is not just a matter of personal preference. It is a matter of choosing who we will become.
