Sometimes devotees think that barefoot parikramā of Govardhana is superior to wearing shoes, or that walking is superior to taking a vehicle.
One should not consider one type of parikramā as superior to another.
Srila Jiva Goswami says in the Gopāla-campū (Pūrva, 15):
svacchandatvād yānam apy atra diṣṭam
“It is not required that the parikramā should be performed by foot. One can also take a vehicle (and obtain the same result)”.
