Prabhupada Letters :: 1970.

"We can understand the Absolute Truth by hearing, that is how we become perfect. Simply by hearing and chanting the Glories of the Supreme Lord from the Srimad-Bhagavatam one can become perfect, this example is shown by Sukadeva Goswami and Maharaja Pariksit."

Prabhupada Letters :: 1972.

"We can never expect any kind of utopia, even in the spiritual world. Wherever there are persons there are bound to be differences. We should not expect any kind of perfect arrangement in this material world."
