Srimad Bhagavatam Canto 10, Chapter 82, Text 46

SB 10.82.46

evam hy etani bhutani
 bhutesv atmatmana tatah
ubhayam mayy atha pare
 pasyatabhatam aksare
 
Translation: 
 
In this way all created things reside within the basic elements of creation, while the spirit souls pervade the creation, remaining in their own true identity. You should see both of these — the material creation and the self — as manifest within Me, the imperishable Supreme Truth.
 
Purport: 
 
One should properly understand the relationships among the material objects of this world, the elements comprising their basic substance, the individual spirit souls and the one Supreme Soul. The various objects of material enjoyment, such as pots, rivers and mountains, are manufactured from the basic material elements — earth, water, fire and so on. These elements pervade material things as their cause, while the spirit souls pervade them in their special role as their enjoyer (svatmana). And ultimately, the material elements, their products and the living entities are all manifested within and pervaded by the imperishable, perfectly complete Supreme Soul, Krsna.
 
A jñani with realization of these facts should feel no separation from the Lord in any situation, but the gopis of Vraja are much more elevated in their Krsna consciousness than ordinary jñanis. Because of their intense love for Krsna in His most humanlike, all-attractive aspect as a young cowherd boy, Krsna’s internal potency, Yoga-maya, covered their knowledge of His majestic aspects, such as His all-pervasiveness. Thus the gopis were able to relish the intense ecstasy caused by their love in separation from Him. Only in jest is Sri Krsna ascribing to them a lack of spiritual discrimination.
