When transcendental devotional service, by which love for Krishna is attained is executed by the senses, it is called Saadhana Bhakti, or the regulative discharge of devotional service. Such devotion eternally exists within the heart of every living entity. The awakening of this eternal devotion is the potentiality of devotional service in practice. — Sri Caitanya Caritamrta, Madhya Lila, 22.105.
If one offers Me with love and devotion a leaf, a flower, fruit or water, I will accept it.
Bhagavad Gita 9.26
A devotee knows that even at his death Krishna will protect him. The real test of our devotion will be at that time.
Devotees are not impressed by the poverty or wealth in material sense in any way; what impresses is devotion.
Krishna is within you and when you are sincerely searching after Krishna by devotion, He reveals Himself to you.
