Oh. Super yay! So, like, visualizing light and hope and joy and positivity actually grows new brain architecture that likely, then, may help sustain you more peacefully and joyfully. Happy neural pathways are real, legit things we, ourselves may influence without drugs of any kind. Meditation, breathing, prayer, aerobic exercise, all probably do this. As do some meds, like lithium, Provigil, possibly, stuff like Adderall. So, get to it. Yoga. Whatever
Just Nike it. And reap the joy.
