SB 11.31.9
saudamanya yathakase
yantya hitvabhra-mandalam
gatir na laksyate martyais
tatha krsnasya daivataih
Translation:
Just as ordinary men cannot ascertain the path of a lightning bolt as it leaves a cloud, the demigods could not trace out the movements of Lord Krsna as He returned to His abode.
Purport:
The sudden movements of a lightning bolt are seen by the demigods but not by human beings. Similarly, the sudden departure of Lord Krsna could be understood by the Lord’s
intimate associates in the spiritual sky but not by the demigods.
