Visualize a green rosebud at the centre of your chest.
Steady your breath.
Allow the rosebud to open with each inhale and exhale.
See the petals unfolding one by one feeling the "openness" while letting go and pushing away any negativity energy or emotion that was trapped in the rosebud or its surrounding space.
Be patient as you slowly bloom.
Pro Tip: If your mind wanders (like mine often does) use a mini mala to keep yourself focused and on task. Seven beads for every inhale, seven beads for every exhale.
