somAnanda (not to be confused with utpaladeva's deshika) describes the thirteen aspects of Kundalini that constitute of shakti vij~nAna, adding three to the list of ten provided in jayadrathayAmaLa:
sthAnaM pravesho rUpaM cha lakShaM lakShaNameva cha |
utthApanaM bodhanaM cha chakravishrAmameva cha ||
bhUmikAgamanaM chaiva antAvasthA tathaiva cha |
vishrAmaH pariNAmashcha tathAgamanameva cha |
iti trayodashavidhaM shAktaM vij~nAnamuttamam ||
They are respectively the seat, penetration or entry, form, object of contemplation, symptoms, the act of raising, the act of awakening, resting at the astral centers, access to the stages, the final energetic state, the silence, radical transformation and return to the Origin (or to mUlAdhAra).
The lakShaNas of vishrAma and pariNAma need to be looked at carefully, even if with notion of kevalAdvaita:
shive vishrAmyate shaktiH tadA vishrAma uchyate |
yatra vishramaNaM shaktermanastasya layaM vrajet ||
tadAtmA paramAtmatve j~nAtavyo nishchitAtmabhiH |
shivIbhUto bhavatyAtmA pariNAmaH sa eva hi ||
These two represent the key aspects of shAkta vij~nAna, pariNAmavAda, and kuNDalinI yoga shAstra.
