Srila Bhaktivedanta Narayana Gosvami Maharaja

'I am happy to give something to you which you can take back in your heart when you will return home. And sometimes, you may chance to open your heart and see that Maharaj has given something and remember and weep, remember and weep. This should glorify your hearts.I am like a street beggar, I cannot give anything, nothing. But I have received something from my Guru-parampara, especially Rupa Gosvami and Raghunatha Dasa Gosvami. I want to give that to you all. But first be qualified.'
(Srila Bhaktivedanta Narayana Gosvami Maharaja)'

The opportunity to hear instructions about the science of the self (atma-tattva) is very rare. Even after hearing them, most cannot realize those instructions because a master who is self-realized (atma-tattva-vit) is very rare. If, by great fortune, such a teacher is available, the students themselves who are willing to hear this topic, are also extremely rare'.
(Katha Upanisad 1.2.7)
