Vini
, while doing the resonance column experiment, noticed that when the conditions
became suitable for 'resonance', the loudness of sound became maximum and it
remained sustained for long. On coming back home, she narrated her observations
to her grandfather. Though he was unable to understand the physics of the
phenomenon, he realised that similar things happen in real life too. He told Vini
that when we align, and orient, our thinking and actions, in an adaptive and
accommodating way, our life becomes more vibrant, happy and productive. We are
then in resonance with the environment and the society.
