Swami Veda Bharati has written:
“Yoga Philosophy views the mind as Universal field; its waves passing through us and becoming our individual minds. This Universal mind is a radiant force and is also known as a Universal Guru within.

When all sit together at the same time even in different parts of the world, they connect to the Universal
Guru mind and generate a strong field, like so many magnets being joined together and forming a much
stronger magnet; the strength of each then equals the combined strength of all.

Thus it is when we join together in meditation, and together enter the Guru-mind’s Field. On certain days
of the year the Wave of Beauty and the Wave of Bliss flows very strong. These are the sacred days.”
