In plain words
A heart full of complete Prema has no fear at all. When we have bought a ticket, put it in our pocket and are travelling by train, we have no fear even in third class. If we sit in first class without buying a ticket, we are afraid all the same. The fear is: when will the ticket collector come, when will he push us out? When we keep in our heart the tickets called Prema for God and faith in God, there is no fear wherever we are. When we do not have this ticket called Prema, at the smallest hardship, the smallest grief, the smallest loss, we sink, waste away and collapse.
We must behold the Paramātma, the very form of Prema, through Prema alone
What is the root cause of fear? The very absence of Prema for God! The very absence of faith in God! A heart that has Prema for God becomes a fine diamond. We can cut a diamond only with a diamond. We must win the Prema of God through the Prema of God alone. To see the shining moon one need not take a torch or a lantern. We can see the moon in the moon's own light. If one would see the Paramātma, who is the very form of Prema, one must see Him through Prema alone. Other paths are of no use at all for this. So Prema is the chief Dharma of man. If we are parted from it, we cannot bear that separation at all. A true devotee cannot endure being parted from God's Prema in the least. The moment they heard the flute of the enchanting Kṛṣṇa, the Gopīs would leave their homes and enter the woods. Those who have read the Bhāgavatam understand this well. The Gopīs who had gone into the forest, unable to see Kṛṣṇa's form and grieving at the separation, went on, it is said, asking every plant, every flower and every tree, "Where is our Kṛṣṇa? Where is our Kṛṣṇa? Tell us!" Thinking that perhaps these plants did not know who Kṛṣṇa was, they went on describing Kṛṣṇa's form, it is said!
The dark one, the one with lotus eyes, the one who sprinkles the nectar of grace upon us, the one with the peacock feather waving on His crown, the one whose face is radiant with a smile, the one who has stolen all we have: O jasmines! Behind your bushes is He not there? Tell us!
