When Sri Caitanya Mahāprabhu took sannyasa Ashram , He immediately desired to go to Vrndavana the most Holy place in Spirtual world where spontaneous love for Krishna is forever and increasingly experienced.
Sri Caitanya Mahāprabhu is setting the perfect example , but on the other hand, as it has been described by our Gaudia Vaisnava acaryas , Vrndavana can be , and is refered to as a state of mind . Wherever Mahāprabhu was that was Vrndavana, and the same applies for His pure devotees.
Once, when Lord Siva appeared to disrespect his father in law Daksya Lord Siva’s wife asked him why he had done so . Lord Siva replied that it was not deliberately done , that he had not stood up to show respect to Daksya . It was because Lord Siva said , “I am always absorbed in Krishna ,” . This is called Suddha Satva consciousness , pure trancendental goodness on a super subjective spiritual plane that can be achieved by hearing pure sound called Sabdha Brahman coming from pure devotees .
In the Bhagavad Gita Lord Krishna speaks of different ways of acquiring knowledge , either from one’s own limited sences , including the mind and intelligence , which is limited, or acceptance of others knowledge and experience ,which can also be limited . Krishna also speaks of knowledge of an impersonal spiritual light, a kind of relief and release from all troubles . Srila Jiva Goswami compares that kind of impersonal liberation to a satisfying deep sleep.
But the highest realm of spiritual realms decends by grace when one practices devotion to God. That is Suddha Satva , the consciousness that Mahaprabhu and Lord Siva demonstrated. That is received from a perfect source someone who is self realised in knowledge of God and who understands applications of the Vedas . Such a person has heard pure sound , accepted pure sound, and vibrates pure sound .
We should also note from Krishna’s pure spiritual subjective thinking that the whole material universe is born , thus, as some physicists understand, there is a curious connection between our willpower and the energies that it can attract.
