At the present moment the human society teaches one to love his country or family or his personal self, but there is no information where to response the loving propensity so that everyone can become happy. That missing point is Krishna and The Nectar of Devotion teaches us how to stimulate our original love for Krishna and how to be situated in that position where we can enjoy our blissful life
(His Divine Grace A.C.Bhaktivedanta Swami Prabhupada, Preface to The Nectar of Devotion.)
Philosophical research culminates in understanding the Supreme Personality of Godhead. After achieving this understanding, when one becomes free from the material modes of nature he attains the stage of devotional service. Either by devotional service directly or by philosophical research, one has to find the same destination, which is the Supreme Personality of Godhead.
(Lord Kapiladeva, Srimad-Bhagavatam 3.32.32)
Give up all fear and shyness and take shelter of the merciful Lord Sri Caitanya Mahaprabhu. He rescues the most wicked of heart, and therefore He is known as Patita-pavana, “the savior of the fallen.”
(Srila Narottama Dasa Thakura, Prarthana)
