Who is Chalchihutlicue?

Answer from the V.M. Samael Aun Weor.

Chalchiuhtlicue: Emerald, precious thing; the one who has a skirt of emeralds. She is the goddess of terrestrial water and wife of Tlaloc. The Nahuas represented her young and beautiful, with a gold tiara, petticoats and a cloak with Quetzalli tassels; in the hieroglyph that adorns her skirt, on the upper inner side of her thighs, a beautiful nymph with a forked tongue appears, a symbol of light.

The Masters invoked her in summer, when the rivers dried up due to drought. On the altar of the temple they placed a pile of sea salt and devoutly implored her help. Afterwards, the Master went to the dry bed of a nearby river and, with the magic staff, in ecstasy, opened two small holes close to each other and filled them with liquid copper that the adepts had previously melted. The Master repeated the invocation and with his hands he widened one of these holes; then, the water gushed forth from the bed of the dry river and began to flow.

Samael Aun Weor. Excerpt from the book: Aztec Christic Magic.

Answer from the Book "The Esoteric Pentagram in Gnosis.".

The goddess of the terrestrial waters; when one contemplates a lake in ecstasy, one is really connecting with this teacher of perfections, when one rejoices with the song of the river that slides on its bed of rocks, when one enjoys the water present in nature, the wife of the rain god Tlaloc is present in an ineffable form.

When there were droughts, she was invoked through rites by our ancestors. The Masters invoked her in summer, when the rivers dried up due to drought. On the altar of the temple they placed a pile of sea salt and devoutly implored her help. Afterwards, the Master would go to the dry bed of a nearby river and, with the magic staff, in ecstasy, he would open two small holes next to each other and fill them with liquid copper that the adepts had previously melted.

The Master would repeat the invocation and with his hands he would widen one of these holes; then, the water would spring forth from the dry river bed and begin to flow. Magical ceremonies, which we should rescue, perform again with great faith, leave behind our crude, vain materialism, break with coarse skepticism and penetrate into the most absolute spirituality. Let us enter into deep meditation, let our minds be silent, deeply concentrated on this initiate and the answer will not be long in coming, it will not fulfill our selfish whims, but be assured that fair requests will be heard.
