Emotional states are like a sine waves. They have peaks and valleys throughout the day, and throughout your life.
They can be other types of waves, too, depending on the intensity and severity of the emotions. But for simplifying the analogy, we'll stick with smooth sines.
There are 2 dimensions when looking at the emotional sine wave:
Amplitude is the peak of the emotion in positive or negative integers.
Frequency is how often those spikes occur close to each other.
It's impossible for a day to not have ups and downs. Even though we'd like to have days where the line is perfectly flat, or super close to the top of the chart.
The chart above is likely close to an ideal day for most people. Not too many highs or lows.
This might be a day where things are rough. Lots of ups and downs. Lots of stress followed by extreme drops in mood that leave you exhausted and sad.
Taking medication, and practicing certain mindfulness techniques, can act as a compressor to your emotional state. Typically, medications act more quickly and reliably than mindfulness techniques.
Mindfulness techniques are wonderful on their own, and if you can get closer to chart 1 on average with them alone, you might not need medication. However, if the techniques alone aren't working, combining medication with those mindfulness techniques can deepen your practice, making it more possible in the future.
The medication acting as a compressor to your emotional sine wave gives you back the energy lost on those peaks and valleys to put towards a deeper practice.
