Ten Maha Vidyas & Srichakra

In Tantra, worship of Devi-Shakti is referred to as a Vidya. Of the hundreds of tantric practices, the worship of the ten major Devis is called the Dasa Mahavidya. These major forms of the goddess are described in the Todala Tantra. They are Kali, Tara, MahaTripura Sundari (or Shodasi-Sri Vidya), Bhuvaneshvari, Chinnamasta, Bhairavi, Dhumavati, Bagalamukhi, Matangi, and Kamala. These ten aspects of Shakti are the epitome of the entire creation. Chapter 10 also outlines their consorts, although
Dhumavati, the widow form, is not allocated a consort.There are several "levels" at which these Devis can be worshiped with the prescribed Mantra and Yantra. Like a simple worship of the yantra with the mantra recitation, as a remedial astrological measure, elaborate worship with all tantrik rituals for attaining various siddhis associated with these tantras and for spiritual salvation.Successful sadhana of these Vidyas gives several boons to the practitioner. The Tantrik-Yogi who has control over his senses and positively inclined uses the boons to guide people and for the benefit of mankind. The ones whose head starts spinning with success use them for the gratification of the senses, gather a bunch of disciples around them and become fake gurus.

The last chapter of todala Tantra equates Vishnu's ten incarnations with the ten Mahavidyas as follows:
"Shri Devi said: Lord of Gods, Guru of the universe, tell me of the ten avatars. Now I want to hear of this, tell me of their true nature. Paramesvara, reveal to me which avatar goes with which Devi.
"Shri Shiva said: Tara Devi is the blue form, Bagala is the tortoise incarnation, Dhumavati is the boar, Chinnamasta is Nrisimha, Bhuvaneshvari is Vamana, Matangi is the Rama form, Tripura is Jamadagni, Bhairavi is Balabhadra, Mahalakshmi is Buddha, and Durga is the Kalki form. BhagavatÌ Kali is the Krishna murti." (Todalatantra, chapter 10)

The worship of these is also prescribed as an astrological remedy - for the 9 planets and the Lagna as follows:

Kali for Saturn, Tara for Jupiter, Maha Tripura Sundari (or Shodasi-Sri Vidya) for Mercury,Bhuvaneshvari for Moon, Chinnamasta for Rahu, Bhairavi for Lagna, Dhumavati for Ketu,Bagalamukhi for Mars, Matangi for Sun, and Kamala for Venus.
The tantrik worship of these most powerful Vidyas must be practiced only under the guidence of a siddha Guru.

Sri Chakra (Sri Yantra) Pooja

"Om Aim Hreem Shreem Sri Lalita Tripurasundari Padukam Poojayami Namah"

Sri chakra pooja or Yantra pooja is the worship of a deity in a diagrammatic form. This type of worship exists in a lot of the other parts of the world also. The worship of Devi in Shreechakra is regarded as the highest form of the Devi worship.

Originally Lord Shiva gave 64 Chakras and their Mantras to the world, to attain various spiritual and material benefits. For his consort Devi he gave the Shreechakra and the highly coveted and the most powerful Shodashakshari mantra, which is the equivalent of all the other 64 put together.
It is said that in the beginning God, who was one, wanted to become many and enjoy himself. As the first step to creation he created Devi - the total cosmic Female force. For the male part, out of his left he created Shiva, out of his middle he created Brahma and out of his right he created Vishnu. That is why many regard the Devi as more powerful than the Trinities and hence She is called Parashakti or Paradevi - Para meaning beyond .
Brahma created the universe. Vishnu controls and runs the universe. Shiva along with Shakti is engaged in the eternal dissolution and recreation of the universe. The Bindu in the center of the Shreechakra is the symbolic representation of the cosmic spiritual union of Shiva and Shakti. Apart from that the Shreechakra also embodies countless number of deities and represents the whole of creation. Hence by worshipping the Devi in Shreechakra one is actually worshipping the highest ultimate force in the Tantrik form.

The Shodashakshari mantra is one of the most guarded secretes of tantra. Usually the Guru gives it to a highly deserving and tested disciple. Very few get it. Even in the Mantra Shastra, where all other mantras are openly and clearly given, the Shodashakshari Mantra is not directly given. Several hints about the mantra are given and you are asked to get the mantra if you are capable and deserving. The opening versus of the mantra shastra chapter on Shreechakra says, "Your head can be given, your soul can be given but the Shodashakshari Mantra of the Devi can not be given".

Various books and websites on Shreechakra have published what the publishers thought is the Shodashakshari Mantra. Let me make it clear that those who know it will never publish it and those who publish it do not know it. So don’t waste your full moon nights chanting those long mantras

However, Shreechakra can also be worshipped by other Devi mantras. There are several traditions of the worshipping the Shreechakra. We are giving here a very simple and still very effective pooja of Shreechakra. It is known as the Shreechakra Navavarana pooja as per the Khadgamala Vidhi. For all round spiritual and material benefits it is a highly effective pooja. Any one can perform it.

If you cannot do a detailed worship, simply worship the Sri Yantra 108 times with the simple Devi Mantra:"Om Aim Hreem Shreem Sri Lalita Tripurasundari Padukam Poojayami Namah"

Or better still with the Panchadasakshari Mantra, which is one of the greatest mantras of Devi and next only to the Shodasi Mantra:

"
