The following slokas from Srimad Bhagavatam indirectly says that Krishna is present at multiple places at the same time
SB 10.59.43: The Lord, performer of the inconceivable, constantly remained in each of His queens' palaces, which were unequaled and unexcelled by any other residence. There, although fully satisfied within Himself, He enjoyed with His pleasing wives, and like an ordinary husband He carried out His household duties.
SB 10.59.44: Thus those women obtained as their husband the husband of the goddess of fortune, although even great gods like Brahma do not know how to approach Him. With ever-increasing pleasure they experienced loving attraction for Him, exchanged smiling glances with Him and reciprocated with Him in ever-fresh intimacy, replete with joking and feminine shyness.
SB 10.59.45: Although the Supreme Lord's queens each had hundreds of maidservants, they chose to personally serve the Lord by approaching Him humbly, offering Him a seat, worshiping Him with excellent paraphernalia, bathing and massaging His feet, giving Him pan to chew, fanning Him, anointing Him with fragrant sandalwood paste, adorning Him with flower garlands, dressing His hair, arranging His bed, bathing Him, and presenting Him with various gifts.
Similarly, are there any other slokas from the same text(Srimad Bhaghavatham) that directly says that the phenomena of Krishna's presence at multiple places at the same time?
