As explained in Wikipedia: this is the process whereby two interacting oscillating systems, which have different periods when they function independently, assume the same period. The two oscillators may fall into synchrony, but other phase relationships are also possible.
These phase relationships also work with people, their relationships, in groups, and the tighter the relationship the more in sync they become. Teams in sync can achieve more than the individual likewise in group meditations, it can be enhanced proportionally. The study of unstable groups and their viral behavior is recognized by researchers, I see it as a high intensity entrainment. Just from proximity and a willingness to surrender to the event seems to create all sorts of phase relationships whether it be good or bad.
During personal relationships we learn our partners cycle of happiness, setbacks, and activities, if we fall into a rhythm that coexists with those characteristics a comfort zone is achieved. It gives one a feeling of security, predictability, and chemistry. Both partners have to be open, and have a willingness to surrender and work within their weaknesses and strengths. The ability to become a good receiver is essential to the equation because an open mind is a flexible ingredient giving one the opportunity to grow and merge together. If the mind resists and fights for ego entitlement, then the synchronicity and subtle frequencies can’t fall into rhythm, growth stops. Being in sync with your partner is the most peaceful and harmonious relationship possible. Arguments will be a relic of the past, life seems almost surreal in the home, without any made up disturbances, your able to float around most of life’s setbacks. A powerful team that can’t be denied is a team that relies on no individual power. One heart beat, its efficient, its easier, its natural, its alert, its productive, and its the most harmonious way of living with your partner.
The great business teams or sporting teams know all of their weaknesses and strengths, come together to work on those weaknesses, enhance the positives, face the hardships together and surrender to the cause. Nothing can penetrate the focus of the team and create disharmony, they continue despite all that has transpired, outside heat won’t make respond out of team character. Any relationships can have a bond like this which is shielded from outside influences so a balance is allowed to flourish within the union. A phase relationship forms from an easy synchronicity that fell naturally into place out of proximity and familiarity. Its all about success in an efficient manner, by allowing the entrainment to prosper within you’ll feel impenetrable or unstoppable due to the strong connections from within.
The same holds true with the Guru and disciple relationship, which allows peace to flow through the group, if one is a good receiver it leaves themselves open to subtle frequencies for peace is noticeable and palatable. If the guru stops his or her mind and meditates with them, peace has a chance to radiate through the whole room and the aspirants fall into a deep meditation. If people are resistant, fighting within or fighting with the teacher then no surrendering can take place. But even that road block can fall for a second and the silent mind wins the moment. Surrendering can happen to the most stubborn minds, and it can turn them on a dime with an epiphany.
