There is a core energy of pure Light, in the central column which runs through your chakras. While your chakras may fluctuate in clarity, according to your emotional & mental state, this core energy remains constant – all the potential of God-perfection, within you. The centre of this column is in your chest, in your place of heart. Placing one or both of your hands on your heart-space, while focussing within, triggers an opening into the softness of your core. You experience this as softening, opening, expansion - a feeling of peace and lightness blossoming within you.
From this place you can choose to tune into the core column which runs through all chakras. You may perceive this as a column of Light, energy, stillness, brilliance – you will have an experience of this unique to yourself – all that matters is that you feel or visualise/imagine this ever-present God-Light through the centre of your core. This is not the prana tube, do not confuse it as such. It is the core essence which holds the potential for perfect enlightenment. Your easiest access to this, in energetic terms, is from the heart, your energetic centre point.
