In the word गुरु Guru, the sound गु Gu echoes the darkness of a cave in which we find ourselves, and the word रु Ru means to get rid of, and indeed these Gurus have helped us immensely in getting rid of the darkness in our lives.
Guru also indicates that which is heavy, and another name for Jupiter, the most massive planet, and thus in this case the Guru means dense with knowledge.
These are the original Seers of the nature of the Universe and humanity’s place in it, whose deep explorations into the uncharted territory of the Mind gave us the world’s oldest recorded literature of the Veda and the illuminating commentary known as the Vedānta Upanishads.
The greatest of these Rishis are those whom we call the Maha-Rishis.
Maharishi Pānini
The Sanskrit grammarian after whom is named the Pānini-Backus-Naur form of computer science grammars for being the first in recorded history, from millennia ago, to formalize a linguistic grammar capable of generating well-formed words and linguistic phrases in the manner of today’s intelligent machines, which wisdom has guided all subsequent linguists of any stripe across human evolution.
Maharishi Patanjali
The master of the Mind Sciences of Yoga, also from millennia ago, who documented precisely the processes of the Mind and how to transcend its limiting concepts, develop psychic powers without getting psyched up about it (for these are mere side-effects of the practice), and attain enlightenment bereft of mental conditioning with perfect clarity of vision of the world around us, and consequently become a living embodiment of the Universe itself!
Maharishi Vālmiki
The first earthly scribe and poet of the Rāmāyana which is probably the most widely read and living epic of mankind, who wrote in lyrical and precise Sanskrit a grand tale of a human’s journey through life and, most importantly in our context, many techniques of Yoga that have been cleverly coded in plain sight which we have surfaced in this book.
According to Swami Vivekānanda …
"Make that one idea your life; dream of it; think of it; live on that idea. Let the brain, the body, muscles, nerves, every part of your body be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced.”
Makes it easier to actually implement Viveka, discriminative wisdom, because we can easily make decisions what action to take based on whether it fits with our goal or not, but the goal has to be all-consuming - and thus we do not waste energy to do the actual work needed.
And hence we get to Vivek-ānanda - the bliss state of perfected choice!
