Transforming the atmosphere

1. Take a moment to notice the state of your mind right now.
2. On an inhalation, breathe in any negativity, agitation, darkness, or depression you find there and take it into the sphere of light in your heart, where you imagine it being transformed into clarity, calm, peace, and joy.
3. On the exhalation, breathe these positive qualities into your mind and feel them filling and purifying it.
4. Continue to breathe in the dark and breathe out the light for several minutes.

If it helps, you might imagine the negative as a hot, dark smoke and the positive as a cool, white light.
