Yes , It is innate but my question do they circulate as it supposed to ?
common people nowdays without proper training, won't have that rise much and/or circulate properly.
That requires lot of intensive training for having that rise (i.e.
different breathing & bandha techniques, balancing Ida & Pinggala, etc)
I am not talking here without knowing it, in fact I have been trained in different schools of modality and I am not here to debate with anyone.
so if you mentioned you had that with natural unfolding, maybe the term kundalini that we talk are "different" one or perhaps you were born differently.
