11. Om Sri Sai Sarva Sakthi Moorthaye Namah
Moorthy means Image idol, symbol, embodiment. Baba is the Moorthy of all Sakthis (Sarvasakthi). He has Himself said that He is Mahasakthi come as Mayasakthi (the universal energy come as the deluging energy, that being the reason why we identify Him with the human form that we see). Three Sakthis or forms of energy are mentioned in the Sastras. Since Baba says that His Reality can be glimpsed only by a person who has mastered the Sastras, He is extolled by this Name as the Embodiment of (i) Ichcha Sakthi (ii) Kriya Sakthi and (iii) Jnana Sakthi; the energy that Knows. Baba is the unfailing reservoir of these three, from which all beings draw their supply. So He is Sarva Sakthi Moorthy. The motivator of the will, the deed and the thought is He and none else. Baba guides the will, shapes the deed and formulates the thought.
When He was asked by the astonished villagers, how he was able to miraculously produce things out of nothing, Baba, as a boy of six years, replied "I have a Sakthi which obeys My will". 'That reply was within their ken' -- He said. But, the reality is 'He is all Sakthi".
