yaha binati raghubira gusaim aura
asa-bisvasa-bharoso, harau jiva-jadata`t
`O Lord Rama! I pray to you to free me from the stupidity of my hope, belief and dependence on the matter (world)'.
eka bharoso eka bala eka asa bisvasa eka
rams ghana syama Nita cataka tulsidasa
"As a `cataka' bird lives only on rain drops (it does not drink even Ganges-water), similarly Tulasidasaji wants to have trust, hope and belief only in Lord Rama and he wants to depend only on His power."
In fact only God grants full refuge. As a baby raises its hand to go to the lap of its mother, the mother raises it up by catching its hand, similarly when a devotee, by applying his power, is inclined to God and prepares himself for taking refuge in Him, God grants him full refuge.
Arjuna wanted to get rid of sins, therefore the Lord said _ that He would liberate him from all sins because it is God's nature that howsoever a devotee seeks Him, so does He meet him - `ye yatha mam prapadyante tamstathaiva bhajamyaham' . In fact liberation from sins is not the fruit of refuge.
By exclusive refuge a man being inseparable with God, can attain infinite bliss. Therefore a striver, without having the desire to be liberated from sins or sufferings, should take refuge in God. If a striver has some desire, he gets something (perishable) but if he is totally free from desire, he gets all (imperishable or endless). God offers Himself to the devotee, becomes submissive to him who takes refuge in Him and feels indebted to him.
This refuge is the gist of the Gita which the Lord has related by showering His special grace. In this `refuge' only, the gospel of the Gita attains perfection. Without it the gospel of the Gita would have remained incomplete. Therefore when Arjuna surrendered himself totally to God, by declaring, that he would act according to the Lord's bidding `karisye vacanam hatava', after that the Lord did not sermonize.
