Golden SunRise, really delighted to learn that you have utilized Cosmic energies of VK successfully. But you are right in saying that Spiritual Development should be left out.
As you are already informed, simply keeping VK in touch with you, elevates your Aura, Magnetic field of the body and Chakra performance. But spirituality initiates in your Soul. However, Golden Sunrise may support you in it, there is no Serum for it.
Please refer Chapter 18 of your Manual which explains about Chakras and its activation. Your way is the best way. There is no need to search for a better one. VK works on your thoughts, so why look for a technique. Intend, focus and affirm in the simplest language to clean, activate and elevate. You are sure to get fantastic results.
