A spiritual person following the path of spirituality is utterly alone. The world around him is not a world of things and beings but one of thoughts and memories.
As a seeker walks on the path of spirituality, he encounters the same obstacles in a finer and subtler form at each stage of his spiritual journey. Determined will and undaunted effort are only equipment for success on the path of spirituality.
It is very difficult to measure progress in spirituality. It may be that when a seeker feels exalted and over- confident that he is really making good progress, he may be actually going downhill. On the other hand, it may be that the seeker feels totally lost, confused and in jeopardy may be really making a very good progress.
All forms of meditation and spiritual practices have been a means of turning off the outside world in an effort to open a channel within, through which the higher forces could enter inside, the invisible could be perceived and the presence of the God could be felt.
In higher path of spirituality whenever you attain a state of inner peace, tranquillity, relaxation and is aware of body-mind and soul simultaneously your own body gives definite signs of spiritual advancement or evolution concerning with perfect harmony of nervous system. Harmonization and synchronization of one’s natural forces and energies will result with regular practice spiritual techniques.
During puberty our bodies undergoes a series of physical, mental, emotional and hormonal changes that will transition us childhood to adulthood. Some common signs of puberty are like growing up body parts, hair sprouting, getting facial hair, cracking and deepening of voice and sexual development etc.
So there must be some visible and obvious set of standard or milestones which are definite indicative signs of spiritual progress known as spiritual puberty. There are many certain and specific signs by which a seekers’ progress in the spiritual path can be ascertained.
Two very important and observational indicators of advanced progress in spirituality are
Opening of Sushumna Nadi
In human body there are 72,000 nadis or channels through which prana circulates. There are 10 important Nadi out of which 3 are most important.Sushumna is the main Nadi and it flows through the central canal within the spinal cord, is responsible for all spiritual awareness. Ida is situated to left side of Sushumna controls all mental functions while Pingla situated ate right side of Sushumna controls all vital functions of the body.
Ida is related to breathe flow in the left nostril and the parasympathetic nervous system while the Pingla is related to the breath flow in the right nostril and the sympathetic nervous system.
Unless Ida and Pingla are balanced there will be many hindrances to spiritual progress. The balance occurs naturally as a definite sign of advanced spiritual puberty and opening of Sushumna is indicated by breathing through both nostrils simultaneously. When Ida and Pingla are flowing together the third flow of Sushumna Nadi is opened.
In higher spiritual path when the body [Pingla] and mind [Ida] are balanced and synchronised a third force spiritual energy arises this is the definite sign of spiritual puberty when you will breathe from both nostrils simultaneously.
Khechari is induced naturally to a seeker in higher state of spirituality. It is a neurological switch which indicates the state of a purified nervous system. Khechari is an ecstatic connection that illuminates our entire nervous system. It is the higher spiritual practices which send us into Khechari, when every cells or fiber of our being wants self-realization or enlightenment the tongue will automatically roll back and go up or in mild form may touch the upper palate.
Khechari fosters the major sexual neuron-opening in the head. Khechari as a spiritual puberty is a constant internal orgy of radiating ecstatic bliss which indicates the sexual union of Shiv and Shakti or Yin and Yang.
So opening of Sushumna Nadi or breathing from both nostrils and Khechari mudra or rolling back of tongue and touching upper palate are the definite signs of spiritual puberty resulting from purified and enlightened and illuminated nervous system. These two signs indicate the higher spiritual transformation of the seeker.
