What we wish to stress at this time is this – that when you focus on your prana tube – and when you make the intention to extend it above and below – your ability to ground yourself, to heal yourself and to recharge yourself is magnified exponentially. Moreover, your ability to tune into awareness of your prana tube at will, at any given moment, will give you the power to control your energy field more efficiently. You will be able to expand or contract your Light body more easily when it is appropriate, to activate your Merkaba Light field, and so forth. Tuning into your prana tube is one of your ‘energy A-B-C’s’; it a requirement for your transition into your multi-dimensional expressions on Earth.
....
We repeat - never let go of the feeling of the heart space when you are focusing on the prana tube - for Love is the most powerful force for healing within you. No energy techniques are truly healing without your ability to be in your heart space. No true transformation within you is possible without Love.
