The Lord responds not merely to the sweet voiced Kokil (cuckoo) and its song; He gives ear to the warbles of other birds, too. He gives ear to the wailings of every being. In fact, suffering entitles you more to the Grace of the Lord. When suffering comes in waves, one behind the other, be glad that the shore is near: bear them bravely; do not like cowards throw the blame on some outside Power or develop dislike for the Lord. (SSS Vol.2)
The Lord will manifest where and when you yearn for Him; if you yearn that He should come before you in flesh and blood, He will respond. He is ever ready to respond; only, you are not ready to invite or welcome or receive Him into your heart. You have not purified the heart and removed therefrom the thorns of lust and greed, of envy and hatred. (SSS Vol.2)
Do not calculate or weigh the reaction, result or reward. Love calls; love responds. Love is God, live in Love. (SSS Vol. 10)
The Bhagavatam shows how the Lord responds to the yearning of the devotees and assuages their anguish caused by separation from the Lord. (SSS Vol.16)
People should realise that God responds only to deep and genuine devotion. Verbal supplications will not suffice. The devotee must acquire the yearning that will melt the heart of God. Even butter which is so soft melts only when heat is applied. Likewise, the warmth of Bhakti (love of the Lord) has to be applied to the butter of the human heart to make it melt. It was their intense devotion which made Krishna dwell in the hearts of Gopikas. They became God-intoxicate. (SSS Vol.27, 1994)
God responds according to your feelings towards Him. If you have purna bhakti (unwavering devotion) and love God with all your heart, He will confer on you purna ananda (supreme bliss). (SSS Vol.39, p. 42)
