What's the purpose of meditation?

[anagogy]

I don't have to worry about a job, but I still feel anxiety.

Usually, emotions arise based on what you are focusing on. Something is on your mind and yet, you haven't become wholly conscious of it yet.

When you feel anxiety next time during meditation, just watch. Where is your attention going? Your attention is inordinately upon something that is stressing you out, causing the anxiety to arise. Anxiety is basically focus on some potential negative thing happening to you. Future based.

No one can know what that is but yourself. Thought/attention can be infinitely subtle, so it may take some time to figure out precisely what it is. But with enough sincere desire to find out, it will made conscious for you. Just like a lock smith gets so sensitive with their fingers, through countless hours of practice, that they get to a point where they can feel each pin unlocking, so too can your awareness become so pristine and sensitive that you are able to feel that barrier which is stopping the free flow of undistorted intelligent energy, resulting in the anxious emotion.

At least, that is how it works with me.

Best of luck.
