OM SRI GURUBHYO NAMAH SRI PARAMA GURUBHYO NAMAH
SRI PARAMESHTHI GURUBHYO NAMAH

The slokas 83 to 102 in the second ch of Varivasya rahasya and Slokas 51 to 68 in the Mantra sanketa part of Yogini Hrudaya describes the Koulikartha to Sri Vidya PanchadasI Mantra.

In short, Sri Chakra,Sri Vidya, Sri Para devata, Guru and Sishya all are one and there is no difference among them is the Koulikartha.
Such oneness is established by showing all these have in common the Ganesha Roopa, Graha Roopa,Rasi Roopa,Nakshtra Roopa,Yogini roopa and Peetha Roopa.

Three La karas of the mantra are three lines of Bhupura in Sri Chakra. There are three circles in the Sri Chakra having 16 Lotus petals and 8 Lotus petals in it. These three circles represent Water element, Jala tatva formed by Sa kara. Sa kara is energy, Shakti. 16 and 8 Lotus petals surrounded by three lines together represents 2 Sa karas in the Mantra.
HREEM kara has in it Ha kara Ra Ka kara also called as Refa, I kaara, bindu and Nada.
9 letters in 3 HREEM karas forms the Navayoni Chakra. Three Ka karas and E kara forms the Bindu in Sri Chakra.
This establishes the oneness of Mantra & Sri Chakra.
Paradevata is the Gross form, Mantra is the Subtle form and Sri Chakra is the Causal form and hence there is no difference between Devata,Mantra and Sri Chakra.

The Avarana Devatas or subsidiary deities surrounding HER are none other than HER rays of incomparable brilliance and hence these Avarana Devatas are called GANAS and SHE is GANESHI.

According to Yogini Hrudaya there are 111 GANAS surrounding HER,where as Sri Lalita Sahsranama says “ MAHA CHATUSHASHTI KOTI YOGINI GANA SEVITA” I will speak about this on some other occasion.

Sun, Moon and Fire are the three eyes of Paradevata, She is the embodiment of Iccha kriya and Jnaana Shakti,the energies of thought, action and knowledge as well She rules over Satva Rajas and Tamo Gunas, together makes 9 and thus SHE is GRAHA ROOPINI.

Five Organs of action,five Sense organs, (Karmendriyas and Jnanendriyas) 4 Amtah karanas ( Inner organs, thinking faculty, Consciene) Ten objects of senses, Prakruti and Purusha, together makes 27 and thus SHE is Nakshatra Roopini.This is according to Sri Bhaskara Makhin, whereas Yogini Hrudaya depicts Nakshatra Roopini in a different manner. Let us not get into debate on which is correct by which we derive no benefits. Finally, if we understand SHE is Nakshatra Roopini that will suffice.

Human body is said to have 7 subtle or Psychic centers known as Chakras. Leaving aside the 7 th chakra Sahasrara, they are 6 and each one is the seat of Dakini and other 5 yoginis as well Vajreshwari and other 5 divinities. These 6 Chakras along with Yoginis and divinities represents 6 constituent elements of the body except semen the 7 th constituent.
ParadEvata is seated in Sahasrara ruling all these 6 yoginis and thus SHE is Yogini roopini.
Ten Life forces, five Main and five subsidiary, (Prana, Apana, vyana, Udana,Samana, Naga, kUrma, Krikura, Devadatta & Dhanajaya) Though they are called Vayu and literal meaning is Air, it is proper to call them as life forces. Jeevatma & Parmatma 2, totally 12 and thus SHE is RASI ROOPINI ( 12 Zodaic signs)

As we know,Sri Vidya Pancadashi has three groups or KOOTAS, Vagbhava, Kamaraja & Shakti.
Vowels A to ah in Sanskrit alphabets makes 16,
Consonants Ka to Ta makes 16,
Tha to sa makes another 16
These are the three sides of the Triangle as well Ha, La and Ksha are the three angles of the triangle.
Similarly Para, Pashyanti, madhyama and vaikhari are Vak GANAS and thus Sri Vidya is GANESHA ROOPA

Sri Vidya as we know has three Groups, Three sound forms ( Nada) and three dots ( bindus), together making 9 and thus Sri Vidya is GRAHA ROOPA.
While understanding Sampradayartha we know that Sri Vidya has 37 Letters when 15 are counted with their constituent letters. Ex K + a
HREEM as 3 letters and so on. In this 37 Letters taking out the Vowel A from all the consonants the total letters in Sri Vidya becomes 27 and thus Sri Vidya is Nakshatra Roopini.

Three HREEM, three Groups ( kootas) summing up to 6 are 6 yoginis counted from Dakini and thus Sri Vidya is Yogini Roopa.

We know before the three HREEM in Sri Vidya La kara is there. HREEM is composite letter of 3 letters, adding to it La kara, summing up to 12 and thus Sri Vidya is RASI ROOPA ( Zodiac signs)

Paradevata Pithas are 55, Sanskrit alphabets called Matrukas are 51 and in addition there are Odyana, Jalandhara, Poornagiri and kamagiri Pitha making it 55. So also Ganesha 1, Graha 9, Nakshatra 27, Yognis 6, Rasis 12, all summing up to 55 and thus Sri Vidya and Paradevata are one as they are Ganesha, Graha, Nakshtra, Rasi, Yogini and Pitha Roopas.

Now let us find as to how Sri Chakra is also same.
Sri Chakra is formed out of Lines, Triangles and Petals representing GANAS and thus Sri Chakra is Ganesha Roopa
Vritta Traya, (3) Bhupura,(3) Fouteen Triangles of Chaturdashara Chakta, (14) bindu, Trikona, AshtaKona, , antardashaara, Bahirdasara, Ashta Dala and Shoadasha Dala ( 1 each) summing up to 27 and thus it is Nakshtra Roopa.

Sthiti Chakra, Samhara Chakra, AshtaDala, ShodaSha dala, Vrutta, Bhupura summing up to 6 is Yogini Roopa
Sri Chakra has 9 Avaranas are enclosures and thus it is Rasi Roopa.
Five downward Triangles, Four upward Triangles, Vruttatraya, Bhupura, Bindu each one summimg upto 12 and thus it is Rasi Roopa.
Three Ka karas and I kara form the Bindu, Sarvasiddhi prada, SarvarOgahara Chakra is formed by Three HREEM. Sarvasrakshakara, SarvarthaSadhaka & Sarvasoubhagyadayaka Chakras formed by Two Ha karas and E kara. SarvasankshobhaNa, Sarvashaapooraka chakras formed by two Sa karas. Trailokya Mohana Chakra from three La karas and thus Sri Vidya and Sri Chakra are one and the same.

Sri Bhaskara Makhin in Varivasya Rahasya writes ;

EtatritayabhinaH svagrustadabhedaBhaava naadaaDryaat
tEna gaNEshadimayastadroopayaa ca svayaM tatha roopah

that is GURU, disciple, Sri Chakra, Sri Vidya and Paradevata are not different from one another all these are one and the same.

in Yogini Hrudya it is said

Devya dEhO yatha prOktO gurudEhasya daiva ca
tatpraasadaa Shca SishyO pi tadroopassan prakaaSatE

Once GURU gets into oneness with Paradevata, Vidyaa and Sri Chakra, by the Grace of GURU, the disciple also gets into oneness with Paradevata, Vidyaa and Sri Chakra,
Yogini Hrudaya Concludes Kouilikartha with the verse:
ityEvam kouLikaarthastu kathitE veeravanditE.
O Bhairavi, you are worshipped by those called VEERA- Here is the meaning of Koulikartha.
