Ignorant Person
One who is ignorant of scientific knowledge of the spirit soul does not look inside the body to find happiness in the soul; instead, he goes outside to search for happiness
Srimad bhagavatam 7.13.29,
Srila Prabhupada.
Humility
Beginning of all knowledge comes from humility.
Special Mercy
To show them special mercy, I, dwelling in their hearts, destroy with the shining lamp of knowledge the darkness born of ignorance.
Bhagavad Gita 10.11,
Srila Prabhupada.
Use of Knowledge
Whatever knowledge we acquire should be used in Krishna consciousness.
Ultimate Knowledge
Vedanta means ultimate knowledge. Knowledge is never perfect unless one comes to the point of understanding Krishna. To remain in Krishna Consciousness is actual understanding of Vedanta.
