Sucram it is my understanding that the Root chakra is where the kundalini is stored and cultivated. Therefore its a good idea to begin working from the root up to properly cycle energy through each chakra. The higher chakras will not work at full capacity until the kundalini has passed through the lower chakras.
The Root Chakra is the source of the life force and forms the vital foundation for all the higher chakras. Here, the inexhaustible supply of kundalini energy is awakened. The sushumna, ida and pingala (the three main energy channels of the human body) begin in this chakra.
The Root Chakra is the true seat of the collective unconscious. Through this chakra, the stored knowledge of the collective unconscious becomes accessible. This chakra should always function in harmony with the seventh chakra in order to maintain our inner balance.
I also struggle with yamas and niayamas. The right way or choices in daily life is not always easy. The first book i read on yoga was a book called "Raja Yoga" Or King Yoga. A sort of Mind Alchemy in which the goal is to connect with the most high and activate cosmic consciousness.
I think this thing needs broken down to simplest form over complicating the practice holds alot of people back. I just go in and kind of let the higher self decide.
If you have already activated your energy centers then yes i think you can work with each one individually. thats just my opinion.
This is going to sound a little crazy to most of you. First, i raised the kundalini by the classical methods describe above, however, i also used radionic techniques until i came into the realization of who i am. Classical yoga by the (rishis) Indian system is an incomplete system and was a remnant of a purer practice that was originally practiced in kemet but whose tenets have been lost in antiquity.. There was only one original asana, the sitting posture (full lotus) or sitting in stillness/emptiness in the dark. The techniques were for the cultivation of the life force, ra,chi, kundalini, orgone and the liberation of the spirit from the illusion of the wheel of reincarnation. The chi, kundalini (Serpent) orgone, pi ray, was to give you conscious connection to the real you, higher self, to the physical you the old master realized that the chi, kundalini etc. was actually the thread that connected the incarnations.
I didn't answer the question, you don't have to start at the root chakra, there are many chakras above the sahasrara, which is the seat, there are many, many more above. So if the sahasrara is the seat and it is in the head where would you start? The Gong zhu, actually proceeds down and then up from the higher self down into the incarnations sahasrara thru the seven chakra and then up like what Mantak Chi states about the micro cosmic orbit.
