The meaning of the word Diksha is “Dwiate Dibyagyanam” which means rendering the True Divine knowledge and power, “Khyiate Paparashi” which means destroying the sins of the disciple. Without tantric initiation or Diksha no one can take part in tantric puja and rituals.
There are different kinds of Diksha in Tantras which are detailed below:
01. Mantra Diksha – In this particular rituals the Sadguru gives the Ishtaa Mantra ie. Mantra of disciples’s choosen Deity, for example goddess Kali, Taara, Tripura etc. He should perform tantric tri-sandhya of the Ishtaa devi and perform the general worship during day time.
02. Shaktabhisekh Diksha – In this particular rituals the Sadguru gives the Avisekh ie. sprinkling of the wholy water on the disciple reciting mantras of Avisinchan from Uttara Tantra and giving the Guru Mantra, Shiva mantra and Ishtaa mantra along with Ishta Gayatri. He should perform Pratahakritya, Tantric tri-sandhya, Nitya-Pujan during day time and special worship on special occasions during night following with Patraa Sadan, Balidaan and Homam.
03. Purnabhisekh – It is the most important and essential initiation in tantric discipline. Here the rituals continues for 3 days, 5 days, 7 days & upto 9 days period. There are different rules and complicated rituals and kriyaas that are performed by Sadguru, Acharya and authorised tantric priests.
The Guru gives the Purnabhisekh from the Maha Kumbha (Kalash) by chanting different tantric mantras from Mahanirvaan Tantra, Uttara tantra and Nigamlata tantra according to his school and Guru parampara. The disciple gets the Guru Paduka Mantra, Dusharna Mantra, Ajapa Mantra, Brahma Mantra and Ishta Mantra. Beside this he also gets panchayatan mantra etc.
Through Purnabhisekh the disciple enters into the holy tradition of an “Avadhoot Parampara” and hence from then he gets recognised as a Sacred Avadhoot.
This Guru Pankti gives the disciple his recognition as a truly Purnabhisikt Avadhoot. This Abhisekh entitles the disciples not only to perform Brihat (Detailed) Pratakritya, Tri- Sandhya, Nitya Puja, but also special worship during night with “Pancha Makar” formally known as “Chakra Pujan, Rahasya Pujan or Nisha Pujan.”
By the power of Purnabhisekh initiation the non brahmin disciple or female disciple gets the equivalent status with a brahmin disciple. Here the division of caste and sex dissolves and all becomes a part of the same “Avadhoot Parampara”.
04. Krama Diksha – Krama means gradual upliftment of the disciple through definite process. Here the mantra of Bhagabati Taara and Tripur Sundari is given along with other Mahavidyas.
