The Nodes of the Moon

In addition to the seven planets, the nodes of the Moon are considered very important in Vedic astrology. The North Node of the Moon is called Rahu, and the South Node of the Moon is called Ketu, these two are not embodied planets, they are merely regarded as shadow planets. Astronomically, they represent the intersection point of the orbit of the Moon and the ecliptic.

The North Node of the Moon "Rahu"

Rahu represents the worldly desires, wherever it is placed in the birth chart shows where our desires are naturally expressed into actions. If Rahu is well placed it can lead to worldly accomplishments, prestige, fame and power. If it is afflicted it can create insatiable desires.

Rahu represents cheating, pleasure seeking and immoral acts. Rahu represents poison, drugs and can lead to worldly illusion.

Rahu is related to insanity, neurological disorders and abnormal sensitivities of the mind, especially when it is related to planets like Moon and Mercury. It deals with hallucination, trance, psychosis and paranoia.

The South Node of the Moon "Ketu"

Ketu represents the psychic forces in the subconscious that can cause compulsive behaviors. It is associated with invisible forces, viruses and epidemic diseases.

Positively, Ketu can give a good power of concentration and psychic, spiritual powers. Negatively, it can give doubts, and a critical vision of life that leads to arguments.

On a spiritual level, Ketu can give the capacity for discrimination and detachment from worldly desires. It is associated with spiritual enlightenment and the evolution of consciousness.

The Outer Planets


Uranus represents rebellion and openness for all that is new, unknown and unusual. Uranus represents individuality and unique expression of the self; it is associated with technology, innovation, discovery, and all that is progressive. Wherever Uranus is placed in the chart is where you will experience unexpected developments, sudden changes and some erratic life patterns. For example, Uranus in the 4rth house can indicate frequent changes of residence; in the second house it can indicate a sudden change of finances for the good or bad. The house where Uranus falls in is the area of life that we approach with a sense of individuality and freedom, if it is placed in the 1st house the person may be eccentric, freedom loving, and it is hard to expect their next step. Uranus has an affinity with Aquarius and the 11th house, some astrologers consider it the ruler of Aquarius, however I use the traditional rulerships and thus use Saturn as the ruler of Aquarius. Uranus is related to intuition; it transmits sudden inspiration and lightning insights especially when it is connected to the Moon.


Neptune is considered to be a planet of inspiration, dreams, illusion and confusion. Neptune is associated with spirituality; it opens the doors to spiritual and transcendental experiences. On the positive side, Neptune is the planet of mercy and compassion; it allows the person to give them self to something greater. Neptune is often found in prominent positions in the charts of Psychics, nurses and doctors, it connection to Mercury and Venus can indicate artistic talents. On the negative side Neptune can indicate deception; it is associated with drugs and all kinds of pseudo-realities. Some astrologers consider it the ruler of Pisces; however I stick to the traditional rulerships and use Jupiter as the ruler of Pisces. The house where Neptune sits in the chart shows the area of life in which you may experience disappointment and confusion. The affairs of this particular house may be the door to experience mystical and spiritual insights.


Pluto is the planet of transformation and renewal; it is related to death and rebirth, both physically and metaphorically. Pluto is associated with subconscious forces and all that is below the surface. Pluto is associated with the obsessive desire for power, control and general destructiveness. It can deal with power struggles, jealousy, sexuality, and abuse. Atomic power and nuclear research are strongly related to Pluto. Some modern astrologers consider Pluto the ruler of Scorpio; I stick to traditional rulership and use Mars as the ruler of Scorpio. The house that Pluto occupies in your birth chart is likely to be a source of difficulty, there is the possibility of obsessing about the affairs of this house. The areas of life represented by this house can lead us to experience profound change, spiritual transformation and healing. In short, the house Pluto occupies is shows us where our spiritual and Karmic journey is centered.
