Root to Crown with chakra bija mantras:
I have been performing full chakra empowerment from Root to Crown daily for quite some time now..
I find the energies raised quite pleasant, harmonious, it does indeed makes one feel aware and receptive.The buzz makes me feel really light. So light in fact that at times I felt like i was about to levitate with a small push from my arms.
Crown to Root with chakra bija mantras:
First, this method makes my upper chakras feel way more empowered. This might be due to 'fresh' energy being introduced in these first.
Second and most significant, this method makes me feel REALLY heavy, dense, and powerful. Very similar to invoking earth energy. Like a consolidation and stabilizing of energies. I feel like NAMAH personified.
Which comes back to what you said, Savitar:
With Power, it can become a reality. it begins in your mind, in the upper or inner world and it can take form and manifest in the lower or outer world.
