Ananada means Bliss, pure purifying Joy. This name emphasizes that Baba is the supreme, the Niraakaara come in human form. Sankaracharya says, "this Brahman is Bliss, from which we are seen separated, through upadhis, as drop of water from the ocean and when we attain unity, it is Brahman"; Baba is Brahman, for 'Brahmavid Brahmaiva Bhavathi'. 'The knower of Brahman verily becomes Brahman'. He is "Param Anandaswaroopa".
The Sai who is in man and the Sai who is in the Sun, 'Sa Ekah', He is one. 'In whatever being there is Bliss, whether in man or in other sentient creatures or in the Devas or cosmic beings, whatever may be the vehicle or upadhi, all Bliss is one. All beings live on a small portion of that Immeasurable Bliss" thus says Vedas. The Ananda we get, when we see Him, speak to Him or touch His Feet or when we recapitulate the Darshan, sparshan and Sambhashana that we have with Him, is never-failing, it is invigorating; it is elevating; it is pure spiritual Bliss.
Baba is Ananda Swarupa; He invites all to pour their grief, their pain, their distress at His feet and take from Him the Ananda that He so freely and fully grants. He is the Ocean of Ananda ever the same, undisturbed, unshaken and undiminished.
