Experiment the link between breathing and our emotions

In my case, I feel like the light in my pineal gland goes higher in intensity when I inhale and goes lower when I exhale. This is barely perceivable and it took me a long time to figure it out. Emotionnaly it makes me feel slightly better when I inhale.

I've noticed this during meditation and I think it might be due to the oxygen coming in and increasing brain activity. I've been trying to maintain the same level of emotion when exhaling to see what happened and it works. I've extended the search now and I told myself "if it works with inhaling and exhaling it might work with happy thoughts and sad thoughts". So whenever a disturbing thought comes in I think of something that makes me happy and then I shift back on the disturbing thought trying to maintain my levels of happy energy, and it works. It allows me to melt the bad thought into the good one. In my opinion, it is a helpful way to decondition my emotional responses so that the thought that I used to find disturbing before does not trigger a bad emotional response anymore. Also it does not imply emotional suppression which can be bad for health.
