"This moment of the year is the feast of Light and astrology in itself is the science of the Light,  which comes to us by the Sun. Everything on the earth, starting from the switching between day and night, seasons, years derives from the Sun.
Planets have not light, it derives from the Sun, so every planetary effect eventually depends on the position of the planet in respect with the Sun, and the same  its light and speed.

"3 Scenarios for Leo
When Leo is found in a certain house, we can expect one or more of the following experiences, depending on how much you're able to express your true self without fear or shame:

1) Experience of Personal Significance - You feel like a rock star in that area of life: people love and honor you for who you are, and you love expressing this part (defined by the house) of yourself to others. You will most likely be elevated somehow in others' eyes, in this life area.

The workings of the universe is probably the most important, yet also the most ignored, topic. There have been various philosophies and explanations for the same in ancient scriptures of various civilisations. One of the most significant being the Chinese philosophy on the natural phenomenon of the universe, or the Tao, as mentioned in I Ching (the foundation of Chinese philosophy also known as the Book of Changes). The book explains the metaphysical workings of the entire universe and is the origin of what is called the Yin-Yang school of Chinese thought.

"One of the most famous and interesting subjects of Medieval art and astrological discussion was the thread of cardinal and theological virtues.
The word “virtue” comes from the Latin “vir“, i.e. man. Still in Latin culture the word did not indicate just masculine gender, but a moral code, an unwritten law more important than the written one.
I see somebody found this subject a little confusing, so I want to give some details about it."

"A 9/56 year cycle has been established in trends of US and Western European financial crises since 1760 (Funk, 1932; McMinn, 1997). Clearly many major financial crises are precipitated by some mechanism, as they tend to occur preferentially in patterns of the 9/56 year cycle and not as random events. Numerous cosmic factors were examined for some link with the timing of financial crises. Sunspots and traditional astrology were the initial areas favoured for assessment but no significance could be realised.

"The glyph for the Sun is composed of the circle of Spirit with a central dot indicating the manifestation of Spirit in the microcosm as individual autonomously creative beings. The Sun is constant, evokes a reserve of power, radiated outwards in all directions, and stands for the principle of individualisation, which when positively expressed brings magnanimity; when negatively, egotism. It describes the conscious, the ego and core identity of any person, and his or her function as a centre of creative self-expression, and awareness of a destiny to attain or purpose to fulfil.
