SB 11.9.21
yathornanabhir hrdayad
urnam santatya vaktratah
taya vihrtya bhuyas tam
grasaty evam mahesvarah
Translation:
Just as from within himself the spider expands thread through his mouth, plays with it for some time and eventually swallows it, similarly, the Supreme Personality of Godhead expands His personal potency from within Himself. Thus, the Lord displays the network of cosmic manifestation, utilizes it according to His purpose and eventually withdraws it completely within Himself.
Purport:
One who is intelligent obtains spiritual knowledge even from an insignificant creature like the spider. Thus, transcendental knowledge is visible everywhere for one whose eyes are opened in Krsna consciousness.
