Hi,
Not into 'spirituality' as such, I do have a passion for medical astrology.
U.S. medical astrologer Ingrid Naiman (www. astroheal.com) once gave a seminar at the astro. school I attended which, literally, 'revolved' around the endocrine glandular system and the individual planetary rulership. She explained how each gland corresponded with/to a chakra.
'Blockages' represent a manifestation of Saturn's physical influence in the form of depresseion/suppression, although
REpression could infer a Pluto influence.
If you are experiencing a chakra blockage, I would assume this to mean that there is a harsh aspect between the planet that represents the gland=chakra
with another.
Google 'Astrology - endocrinology' and/or 'Astrology -chakras' and you will find umpteen sites that offer information that you may find helpful in working out the equation for yourself.
