Aditenumanyasva : Aditi ! mother of Gods, give me permission to do this.
Anumatenumanyasva : Anumati ! give me permission to do this.
Anumati Oonachandraa Poornamaasee : Anumati is that Purnima where the moon is not full or Purnima Tithi with touch of Chaturdashi or Pratipada. This Tithi is accorded divine status.
Sarasvatenumanyasva : Sarasvati ! goddess of speech, give me permission to do this.
Deva savita prasuva : Savita ! give me permission to do this.
