SB 10.76.21
bahu-rupaika-rupam tad
drsyate na ca drsyate
maya-mayam maya-krtam
durvibhavyam parair abhut
Translation:
At one moment the magic airship built by Maya Danava appeared in many identical forms, and the next moment it was again only one. Sometimes it was visible, and sometimes not. Thus Salva’s opponents could never be sure where it was.
