The manifestation of unadulterated devotional service is exhibited when one’s mind is at once attracted to hearing the transcendental name and qualities of the Supreme Personality of Godhead, who is residing in everyone’s heart.
Srimad Bhagavatam 3.29.11-12,
Srila Prabhupada
One who acts to serve Krishna with his body, mind, intelligence and words is a liberated soul, even within this material world.
By rendering devotional service unto the Personality of Godhead, Sri Krishna, one immediately acquires causeless knowledge and detachment from the world.
Lord has sent the rope of bhakti to pull all the conditioned soul suffering in dark well of illusion… hold firmly.
The Kingdom of Godhead is not a myth but it is situated far beyond the boundary of the material cosmos and one can know it by the process of devotional service only.
Devotional service is dependent on the mercy of Krishna and His Devotees. Unless we surrender to the lotus feet of a pure devotee, it is not possible to come to the platform of pure devotional service. By his own efforts a bee cannot taste the honey within a bottle. The bottle must be opened by a superior. If the bee simply licks the outside of the bottle, thinking “Now I am tasting honey,” Then he is in illusion. Similarly, no one can enter into devotional service unless the door is opened by a devotee.
