For advancement of material knowledge there is a need for personal ability and researching aptitude, but in the case of spiritual knowledge, all progress depends more or less on the mercy of the spiritual master. The spiritual master must be satisfied with the disciple. Only then is knowledge automatically manifest before the student of spiritual science.
Knowledge is useless if it doesn’t create remembrance of God.
Vedic knowledge means hear first, see later.
Real knowledge flows, from guru to sisya, not through words but through consciousness.
Genuine spiritual knowledge or vijnana means “I submit to the Vedas” whereas material knowledge means “knowledge submits to me & works for me.”
Krishna is everywhere, Krishna is in everything. Srimad-Bhagavatam gives us that knowledge by which we can see Krishna everywhere and in everything, and understand where we are now and where we have to move to, by a scientific process — scientific process in the sense that if we follow the stipulations, then we get the result; and if we don't, we don't get the result. If we chant the holy names of Krishna without offenses, niraparadhe nama laile paye prema-dhana, then we attain love of Krishna; and if we don't — if we chant the names of Krishna with offenses-then, bahu janma kare jadi sravana-kirtana tabahu napaye Krishna-pade prema-dhana: even if we supposedly chant the names of Krishna for many lifetimes, we won't attain love of Krishna.
