Sri Pardhasaradhi Ayyangar from Madras, was sitting with Amma on the portico enjoying the pleasant evening breeze. Suddenly Amma began to stare into space with a far away look. After Amma returned from the mood, Sri Ayyangar asked Amma what she was staring at. The unexpected reply was: 'thought waves'. By a series of probing questioning, Sri Ayyangar elicited the following information.

Amma was just observing thought waves passing by in space. They were all knotty, twisted, and distorted. But as they approached Amma, all the twists and distortions disappeared, became straight and passed on! Did Amma wish the wonderful transformation? No. She was just observing.

It means Amma was, by her mere presence, acting as a great purifier of thoughts that are so effective, so powerful and so vital. By transforming the negative thoughts into positive thoughts, the very thinking process of humanity is transferred to more benevolent channels. All this is taking place all the time without any fanfare or publicity! More important - the process is still continuing.
