Why Anagha Vratam?
Anagha means sinless. In general, we commit number of sins by thought, word and deeds and these sins prevent us from progressing in daily life. The divine couple who destroys these sins are Anagha Swami and Anagha Devi.
Lord Dattatreya (Vishnu) is worshipped in a very graceful householder's avatar in addition to the famously known ascetic forms. This very form is called as Anagha Swami, where His consort is called Anagha Devi - She who can make all of us cross this ocean of bondages and Karma. The eight Siddhis that anyone can attain, are worshipped in this method as the effective children of the Lord Anagha Swami and Goddess Anagha Devi. This in a way shows our interest in spiritual saadhana to attain the siddhis and thereby reach salvation (or Mukti) to reach the abode of Lord Dattatreya - which is the absolute bliss.
