Meditation brings happiness?

[Delmo]

When I meditate, I become more aware on my surroundings, less thoughts and no extreme  emotions(like very happy or sad). An experience of the present. 

The other day I was in a extreme happy state, when I meditate it went down from very happy to "normal" state, which I didn't like much in comparison. 

My privous thoughts on meditation was, it multiple your positive emotions so you become more joyful. But that didn't work on me. Am I doing it wrong or is it a time factor?

Don't try to manipulate the meditation, then you're not allowing.

Meditation is all about becoming 110% present and allowing all feelings negative + positive, don't cling to the feelings or thoughts, just allow, allow, allow, and watch the emotions and thoughts pass again, notice the impermanence. Keep doing this over and over again, and a sense of general bliss will flow over you

it does, overthinking causes more cortisol, when you let go and focus on your breath, the more happy chemicals can start flowing

@Delmo Surrender fully in meditation, surrender emotion, surrender “states”, surrender experience - surrender your self. Trust is the fulcrum of the op, imo. What lies ‘beneath’ your positive emotions is far greater than any multiplication of them.

@Delmo Once it becomes effortless, it does bring intense joy, rapture, happiness but it does take time and effort to get to that stage.
