If your energy needs a boost and needs as well to be harmonised, you can use the mantra
It is another way of directing your kundalini power.
You can use that mantra as well if you feel low on energy.
You can use it in a dynamic way, for instance uttering it while you jog or train in a rythmic way.
You can as well sing it when in nature or use it in association with a breathing technique.
To your Yoga!
