Srimad Bhagavatam Canto 11, Chapter 29, Text 12

SB 11.29.12

mam eva sarva-bhutesu
 bahir antar apavrtam
iksetatmani catmanam
 yatha kham amalasayah
 
Translation: 
 
With a pure heart one should see Me, the Supreme Soul within all beings and also within oneself, to be both unblemished by anything material and also present everywhere, both externally and internally, just like the omnipresent sky.
 
Purport: 
 
According to Srila Visvanatha Cakravarti Thakura, the Lord has spoken the present verse to attract those who are inclined toward philosophical speculation about the Absolute Truth. Such transcendental scholars searching for the ultimate unity will be attracted by the Lord’s manifestation described here.
