There is a minor chakra located in each hand. The color of these minor chakras is pink. There are some ways you can use these chakras to heal situations or transform negative energy into love:

1. If in a confrontation with someone and they throw something verbal at you, you can instead of responding in an confrontational manner back, visualize catching that energy/verbal assault (or whatever it may be) in the pink chakra of the hands.  Know that within this chakra it is being disolved or tranformed into love and then visualize sending that love back to them. See if there is a change in their reaction. They may get tongue tied or you find there approach soften. The trick is to remembering to do this before reacting which can be easier said than done... :P 

I've even enjoyed using this technique on barking dogs .... I visualized catching their barks in the pink palm chakras and sending it back to the animal tranformed into love. It works pretty surprising at times. The dog sometimes stops barking and becomes more peaceful or at least more curious.

2. You can also use this technique on your own attacks that you make upon yourself or others. Just visualize catching negative comments you make to yourself in your palms when you find yourself attacking yourself or distressed over an issue you feel upset over. Imagine it delivered into the pink chakra and being transformed into love which is either sent to yourself or another person in question. 

3. A third way I like to use the chakras in the hands is in energy work. I like to start by visualizing a pink beautiful cloud of energy around my hands (it doesn't have to be emanating from the hands, just surrounding it). I usually use a prayer of intention, such as asking that my hands be as God's hands and the energy channelled is God's loving energy, asking that I be a pure and perfect channel. Then, I run my hands over my body and energy field imagining that any negative energy is being magnetically pulled into that pink cloud and is transformed into love which is then sent into my energy field. Sometimes I work the different layers of the energy field this way. You can also try it for pain or over-thinking. I put my hand on my head or where the pain is, either directly on or above and then imagine the pink cloud around my hands and that the negative thoughts or pain is being absorbed by that pink cloud and transformed into love which is returned back into that part of the body.
