Cosmically, and therefore collectively, we are in a huge contraction phase. We can see this in the alignment of the planets, specifically Saturn conjunct Pluto, and we don't have to look far to see it in nearly all aspects and systems of our life right now. It is no coincidence. Historically speaking the planetary alignments similar to the current chart coincided with major historical events, that as one cosmologist, Richard Tarnas in his book Cosmos and Pysche, says represents a contractive period. Where conflict and violence dominate not just in one locale, but across the globe. Saturn governs authority, solidity, security, tradition, status quo, order and system. Pluto governs the dark shadow and represents transformation. He also says in this book, that periods of contraction are almost always followed by alignments that have repeatedly been creative and innovative. Expansive!
In this seemingly world of duality, we need to remember that one cannot be separate from the other. Polarizing forces coexist. Just like when day turns to night, the same sun continues to shine on Earth. From the sun's perspective, nothing has changed. So, ultimately reality is non-dual. Duality is a matter of perspective.
Yoga teaches us that we are always under the influence of the gunas, or the qualities of nature, which includes the opposing, or complimentary, forces of tatvas (inertia) and rajas (action). We will find ourselves operating from one of those forces at any given moment. The practice can direct us towards sattva, harmony between the extreme fluctuations of tattvas and rajas. This is the space in between.
The space in between can be mirrored in the heart center, or heart chakra. In fact it is central to our lower and upper halves and energy centers, it is central to left (masculine) and right (feminine) sides of our body, it is central in how we connect emphatically with one another, it is central to compassion. It is central to our electromagnetic field that has immense capacity to expand and hold within it both ends of the spectrum and all the possibilities that have yet to be known. Our heart beat is like the undying steady pulse of the universe.
As we can see with the innate rhythms of nature and the planets, it is all cycles within cycles. One continuation from one extreme to the other. Synching to this rhythm is presence, is yoga, is freedom. Pure presence can be expansive for the mind as it is detached from either/or thinking. Pure presence is tapping into the field of potentiality. Here we are more open to receive new ideas, solutions or new ways of thinking and being that are beyond our current familiar dualistic experience.
