Srimad Bhagavatam Canto 12, Chapter 06, Text 32

SB 12.6.32

param padam vaisnavam amananti tad
 yan neti netity atad-utsisrksavah
visrjya dauratmyam ananya-sauhrda
 hrdopaguhyavasitam samahitaih
Those who desire to give up all that is not essentially real move systematically, by negative discrimination of the extraneous, to the supreme position of Lord Visnu. Giving up petty materialism, they offer their love exclusively to the Absolute Truth within their hearts and embrace that highest truth in fixed meditation.
The words yan neti netity atad-utsisrksavah indicate the process of negative discrimination, by which one engaged in the search for essential and absolute truth systematically rejects all that is superfluous, superficial and relative. Throughout the world people have gradually rejected the ultimate validity of political, social and even religious truths, but because they lack Krsna consciousness they remain bewildered and cynical. However, as clearly stated here, param padam vaisnavam amananti tat. Those who actually desire perfect knowledge must not only reject the nonessential but must also ultimately understand the essential spiritual reality called param padam vaisnavam: the supreme destination, the abode of Lord Visnu. Padam indicates both the status and the abode of the Supreme Personality of Godhead, which can be understood only by those who give up petty materialism and adopt the position of ananya-sauhrdam, exclusive love for the Lord. Such exclusive love is not narrow-minded or sectarian, because all living entities, being within the Lord, are automatically served when one directly serves the supreme entity. This process of rendering the highest service to the Lord and to all living entities constitutes the science of Krsna consciousness, which is taught throughout Srimad-Bhagavatam.
