What is perceived through senses and sense activity is called knowledge. But there is a higher knowledge gained when the mind is disciplined by concentration and meditation. This is known as the power of yoga by which the experience of transcendental consciousness is possible. It is then possible to enter into the past and future as well in this state. The Lord is the master of infinite yogic power of unfathomable range, and out of His Sankalpa He assumes suitable forms during His incarnations, pointed out Swami Gautamananda in a discourse.
While imparting the higher truths to Arjuna, Krishna chooses to reveal a part of His supreme yogic power to Arjuna and also enables him to understand its tremendous significance. Arjuna is overwhelmed that the Pandavas who have placed their trust and faith in His yogic supremacy are protected by Him. He foresees the impending fall of the Kaurava army comprising the greats such as Bhishma, Drona and others and also realises that he and the Pandava army are merely a ploy to accomplish this task.
The Lord is ever aware of the workings of the universe — from the celestial worlds to that of the lower beings inclusive. Every act, thought wave, speech, etc, of every being is transparent in His consciousness. As a child, Krishna is thus able to defend Himself against Kamsa’s threats. While those in Gokula never suspect the ulterior motive of Putana who assumes the form of a lovely maiden and with seeming affection tries to fondle the child, her deception is crystal clear to Him and He takes necessary action against it. No wonder Nandagopa, Yasodha and the entire Vraja people are awe-struck by the child’s extraordinary feat in this case as well as when other demons in various forms try to kill Him.
