Simple article on chakra purification:

There are a variety of hatha and kundalini yoga poses to open your heartspace in a more physical way.
I'm not an expert, but a simple one I picked up For the heart chakra is using the technique of setting the intention to purify and open the anahata. Relax into a meditation in lotus, and focus pranayama breathing on your heart chakra. Imagine each time you breathe in, visualize 12 petals opening wider and wider, and closing as you exhale. It's not going to blow you wide open, but will help you to realize the varying degrees that you can operate at. This style is just a quick meditation type that I never exceeded 15 minutes.
