na początek ciekawy tekst o miedzi, faza zielona, indygo i zółto-złota:
http://www.theosophytrust.org/632-copperAphrodite, Ishtar, Isis-Hathor or Io – they are all aspects of the same sacred spirit watching over the earth, so beautifully typified by Venus, who gives to her adopted offspring one-third of the light she receives from the sun. Venus is Freyja, whose sacred day is Friday, and her beneficence manifests in the earth through the soft glow of copper. This is her gift which has played such a crucial role in quickening human consciousness. Dissolve her metal and one obtains an indigo fluid, the colour of which is symbolic of the higher mind. Rub the indigo and a copper lustre reminds one of the great love exemplified by Venus. In her Nordic guise Venus as Freyja was worshipped by the Valkyries, who were so eager to become brides of the heroes and gods. As Frigg, she was the wife of Odin and queen of heaven, draped in the indigo of the Cosmic Sea. Indeed, Venus is the personified sea and mother of the god of love. She is Lakshmi and Stella del Mare as well as "the most occult, powerful and mysterious of all the planets".
The Egyptians believed that Venus nourished the divine spark in man, which was Osiris (the bound or mummified Sun), so that it would become a flame capable of rising like the morning star. This Venus, or Isis-Hathor, is the same as the Babylonian Ishtar, the goddess who begot mankind. It was believed that Ishtar entered into the underworld and passed through all of its seven gates. At each portal she was divested of her crown, jewels and finally even her garments, until she stood naked in front of Allat, the queen of Hades, who inflicted upon Ishtar the diseases of each part of the body. But Ea commanded her release, and her mission ended successfully. This wonderful myth describes the fall of Venus (Virgo) into the pit, the descent of the human soul by even stages into the bondage of matter. Losing its divine powers one by one, the soul is corrupted by mental and physical diseases until it finally receives the aid of the higher divine will. The human Ego develops its consciousness fully at these portals, learning to control the bodies which it constructs from them and to use them effectively as vehicles, so that they may not only serve as bridges to carry impressions from outside to the soul, but can also enable that soul to express itself on their several planes through their instrumentality. At the last portal the soul receives the Aquarian crown of unconditional Divine Love and no longer suffers the rigidity and blockages created by the lower principles.
The principle most likely to create rigidity is that of kama manas or the lower, personal mind of man. Venus in her fall spans the realms of the higher and lower. Just as she is both the morning and evening star, so also she and her sacred copper are symbolic of the dual mind. The Egyptians thought that Isis-Hathor rose from the green malachite lakes to preside over the malachite mines which yielded copper ore.
Thus, the goddess rose out of the green of the lower mind and took her station by the copper yield associated with the indigo of the higher mind. Indigo represents an intensification of the colour of heaven and the upward tendency of Manas as it merges with Buddhi to become the true hermaphroditic god. On the way to this merger of indigo and golden yellow, green is encountered. It is the raw ore or the patina of the mind principle which must be heated and cleansed in order to enable it to express its deeper potential.
