The Ascended Masters Hierarchy and Twin Souls
When one of the soul fragments is of the male energy and the other is that of the female, then that specific pair would be twin souls or twin flames. In addition, they must vibrate at the same frequency.
As an individual achieves a certain level of development, it becomes possible that a counterpart be brought into its life experience on this plane. Recognition would take place on a spirit and soul level. On a material level, it would be subconscious contact with much love and understanding between the persons involved.
Each individual Twin Soul, endowed during its descent into matter with a predominantly male or female polarity, thus acts as a balancing force to the other. One based on an inherently forceful male/active/positive/outgoing characteristic. The other with a more receptive/nurturing/spiritual/in-going female characteristic.
Thus it is that two Twin Souls, or Twin Flames, are created as part of one spirit at the highest level. They will remain forever as eternally joined parts of one soul extension. After ascending and descending through the Cycle of Evolution together, they are eventually destined to reunite at the end of their long evolutionary journey. They will do so as one complete and androgynous Being. Yet they shall forever also be two souls in one and even retain an element of their two polarities as well as their individualism.
