Srimad Bhagavatam Canto 11, Chapter 27, Text 53

SB 11.27.53

mam eva nairapeksyena
 bhakti-yogena vindati
bhakti-yogam sa labhata
 evam yah pujayeta mam
 
Translation: 
 
But one who simply engages in devotional service with no consideration of fruitive results attains Me. Thus whoever worships Me according to the process I have described will ultimately attain pure devotional service unto Me.
 
Purport: 
 
The previous two verses were spoken by the Lord to attract those interested in fruitive results, and now the ultimate purpose of worshiping the Lord is described. The ultimate goal in life is Lord Krsna Himself. Love for the Lord is the highest bliss, although ordinary people cannot understand this.
