Srimad Bhagavatam Canto 11, Chapter 20, Text 35

SB 11.20.35

nairapeksyam param prahur
 nihsreyasam analpakam
tasman nirasiso bhaktir
 nirapeksasya me bhavet
 
Translation: 
 
It is said that complete detachment is the highest stage of freedom. Therefore, one who has no personal desire and does not pursue personal rewards can achieve loving devotional service unto Me.
 
Purport: 
 
As stated in Srimad-Bhagavatam (2.3.10):
 
akamah sarva-kamo va
 moksa-kama udara-dhih
tivrena bhakti-yogena
 yajeta purusam param
 
“A person who has broader intelligence, whether he be full of all material desire, without any material desire or desiring liberation, must by all means worship the supreme whole, the Personality of Godhead.” In this statement by Sukadeva Gosvami, the words tivrena bhakti-yogena are very significant. Srila Prabhupada remarks in this regard, “As the unmixed sun ray is very forceful and is therefore called tivra, similarly, unmixed bhakti-yoga of hearing, chanting, etc., may be performed by one and all regardless of inner motive.” Undoubtedly, in this Age of Kali people are generally very fallen and polluted by material lust, greed, anger, lamentation and so forth. In this age most people are sarva-kama, or full of material desires. Still we must understand that simply by taking shelter of Lord Krsna we will achieve everything in life. The living entity should not engage in any process except the loving service of the Lord. One must accept that Lord Krsna is the reservoir of all pleasure and that only Lord Krsna within our heart can fulfill our real desire. This simple faith that one will achieve everything by approaching Lord Krsna is the essence of all knowledge and carries even a fallen person over the painful hurdles of this difficult age.
