कामिक आगम: पूर्व भाग (अष्टाविंशति मूल शैव आगमों का प्रथम एवं सर्वोच्च आगम महाकोश)

Having transformed his body to be in the likeness of Siva by means of anga nyasa and kara
nyasa, the sadhaka should worship the Sakti known as Sandhya. He should contemplate
Brahmi Sandhya as associated with the qualities of Brahma, during the period of brahma
muhurta. He should contemplate Vaishnavi Sandhya as associated with all the qualities of
Vishnu at the time of noon. He should contemplate Raudri Sandhya as associated with all the
qualities of Rudra, in the evening.

The Sakti who commissions the three Lords , Brahma, Vishnu and Rudra in their respective
functions, who is the unfailing Witness of all the actions of all the souls and who is the spouse
of the Supreme Lord Siva is specifically called Sandhya. Having installed himself within
the effulgence of this Sandhya Sakti, the sadhka should accomplish all those activities which are
to be performed in the morning. Again, he should worship that Sakti of Lord Sambhu with the
orderly recital of mela mantra. Then, the worship of that Sandhya Sakti should be done in a
systematic way, preceded by the incantation of the astra mantra.
