In India, of course our peers have always known of the chakkers! but extensive work has been done on this esoteric science right in Jammu and kashmir, from Lal ded, Abhinava Gupta,down to Swami Lakshman jee and Pandit Gopi krishna in our own age, all of who have been doyens in teaching of this sacred science. The very basics of the science state that a human has seven major levels of existence, each corresponding to a station within his own body, like a vortice or dominative energy field of that particular realm of existence.
So , we have :  Muladhar, The base Chakra below the spinal cord, where Kundalini sleeps, happy with her shelter, and if this Chakra is not transcended,one would lead an existence of food/shelter needs.
This can go on for years, as in the human evolution itself,and
we know that our forefather, the first man, lived as a cave dweller for years before he wandered out to explore.
Even today, though the human race as a whole has evolved past just looking for shelter, the first Chakra dwellers would be those individuals who never rise above material realms.So it can be a moneyed man or even a nation that does not think beyond materialism.  Svadhisthan, The second Chakra at the root of the progen- itive organ, which,appropriately, stands for the procreative need of the individual or race.  Manipura, the third Chakra,at the navel, symbolising the ‘power’ need, a sort of umblical cord of the individual to his higher potential.  Hrdya, the fourth, at the heart,denoting the emotive need.
Behaviours may be better understood at this level.  Visudhha, the fifth at the throat, denoting eloquence. An appreciation of arts and crafts leads to ‘culture’.  Ajna, the sixth, at the forehead, also the third eye, or Gyan chakshu,denoting intuition, again, appropriately, the sixth sense.  Sahasrara, the seventh, over the roof of the head,meaning literally,the thousand petalled, or, symbolically, where the individual becomes, anant- endless,or the Universal itself.
Interestingly, in the outer macrocosm, this is true of sacred geography,and so you may understand even Yatras, to be grad- ual ascents, for example, at Vaishno deviji Yatra, say from Kol kondoli ,to Charan paduka, Ardh kawari, Haathi matha and finally Mata dar- bar at Vaishno devi; or at our Amarnath yatra , beginning from Pahal gam, Chandanwari, Sheshnag,Panchtarni, the Mahagunas, and finally the linga at the top, called Amarnath!
Of course, this is true for even the geographical abode of Shiva, Kailash! where one traverses through various stations,before the culmination of Kailash darsana itself.
You may even realise that the older day maharajas had gar- dens,palaces, even cities designed in the chakra weave, Jaipur , with its pols(gates) may be a fine example of sacred geometry.
Such was the importance given and pointers erected in honour of Kundalini.
Aum Namah Shivaye.
