11.18  Tvam aksaram etc.  Guardian of the pious acts of the Satvatas.  Satvatas are the same as the Satvatas i.e.  those who are established in the Truth that does not take cognizance of any difference between the Action  (11.Spanda)  and the Consciousness;  the Truth which is  nothing but Existentiality and is in the form of Awarenes.  Their  pious act is that  act  [of meditation] of theirs which - on account of its being  continously engaged in the process of undertaking and rejecting  [things] - consists of the act of emanation and absorption,  and is the most superior of  all the paths  [leading to salvation].  The Lord protects that pious act.  This is the secret in this chapter and it has been made almost clear by me  (11.Ag.) in my  (11.Ag.'s)  Vivrti (11.Commentary)  on the Devistotra  (11.Goddess-Hymn).  That is self-evident to the learned readers, with critical accuman, and initiation.  Hence, why to take recourse to the verbiage of explaining again and again what is already known very clearly.
