I have a question about energy work and in particular the major chakras.

I have been working with NEW on and off for the last month now and i can easily feel and move energy over most of my body, i can feel all my major chakras if i wish and i have Astrally projected a few times. When i did NEW i followed directions from the simplified version and after clearing the last lesson i do not know what to do next.

I wonder if i can safely start developing my major chakras at this point or do i need to do anything more with my secondary ones first? I followed the lessons to the last word and have done every exercise numerous times so i think i may be ready but i don't want to work on them if it could hinder my progress later on.

Thanks for replies
