Yes we commune with Gods by meditating on our chakras, chanting mantras, wearing their Rudraksha/Yantra/lockets. But since Gods reside in the chakra, one needs to first realise the chakra fully.
Realisation of chakra means learning all the lessons of the chakra and thus opening it fully. This happens when we transform by awareness on the lessons of the chakra. Just chanting and praying without awareness of the need to transform ourselves, gives little result. And once chakra gets opened, one needs to invoke these energies by mantra chanting. Mantras work by law of attraction.
The more you attract by joy, pleasure, command, contentment, gratitude, bliss.. they work.. If you invoke by fear, sadness, pain, helplessness.. they don’t work.
