Simply put, it says: "Do not Grieve." Swami
Venkateshananda says that we should use this verse as a mantra. When
worry knocks at our door – which it does, when grief threatens –
as it does, let us visualize Sri Krishna standing before us, saying,
"You are worrying unnecessarily." Thinking is essential.
Worrying is not only unncessary, it actually prevents thinking.
Through hundreds of fascinating episodes, this most beloved God
has established a code of conduct and a set of values that are
singularly Hindu and yet universal in application. The core message
is also the core philosophy of the Hindus i.e. the framework of
Dharma within which we are asked to serve society even as we enjoy
life on this earth.
