In numerology, the number six indicates a balanced personality. People who predominantly display features of the six are responsible, idealist, caring, unselfish, teachers, protectors, charitable and have emotional depth.
The negative aspect of the six is that you are disconnected, hypocritical, weak, shallow, submissive, restless and easily stressed.
People who have too much energy from the six are pulled in different directions by others to the point they are continually giving and being distracted from what they really want to be doing, or should be doing.
In esoteric teachings, the symbolic meaning of six is often represented by the hexagon, sometimes formed by two overlapping triangles as we see in the Star of David and Seal of Solomon.
Taken at face value that doesn't really mean anything. When you understand the esoteric meaning of the Star of David and thus the six, you can appreciate the "divine union" actually means the integration of unconscious content into the conscious mind.
The male is symbolised by the upward-facing triangle and represents the conscious mind. The unconscious mind is the down-facing triangle.
The six is, therefore, denoted when split-off consciousness crosses over from the darkness of the unconscious into the light of the conscious mind - the joining together of two opposites.
You can read more about the union of opposites in this article, the esoteric meaning of the hexagon. Meanwhile, you may be interested to know this:
“The number 6 is most skilled in begetting, for it is even and uneven, partaking both of the active nature on account of the uneven, and of the hylical nature on account of the even, for which reason the ancients also named it marriage imd harmony … And they say also that it is both male and female … And another says that the number six is soul-producing because it multiplies itself into the world-sphere, and because in it the opposites are mingled.” ~ Carl Jung, The Practice of Psychology, CW 16. par 451
The Bible reflects the same principles given in numerology. The symbolic meaning of six in Christianity represents human weakness, someone who is not able to overcome temptations. In the creation story, man was created on the sixth day.
The six is base consciousness and only by transcending to the seven will you gain a better understanding of life, improve your personality or work with the laws of nature.
The number of the beast – 666 – represents the point when a man is enslaved by his basic nature in body, mind and soul. 666, therefore, represents the animal nature of man when we enter the physical plane.
“The bringing together of three 6's is the number and mark of the end time Beast of Revelation. As such, it represents the very best system of governance that mankind can produce WITHOUT God and under the constant influence of his chief adversary.” ~ P. D. Ouspensky, Symbols of the Tarot
Like in many eastern religions the purpose in life is to liberate the mind whereby you will transcend from base consciousness to higher consciousness.
When sixes continually appears in your life, you have to find a way to balance your time and your emotions. You need the strength to say no and not take on too many responsibilities that burden you despite your innate intuition to help and serve others.
The esoteric meaning of the six relates to self-awareness.
Sometimes, the sixes will be an indication that you need to allow the contents of your unconscious into your conscious mind. Observe your thoughts and feelings and ask yourself whether a repressed emotion is trying to break free. The qualities we need to develop are always in the unconscious.
If you do not take time out to care for your own needs, try to improve your character traits and resist temptation, you cannot move into a state of self-awareness that leads you along the path to the higher self.
