When we ask from Krsna anything other than devotional service, that is pious activities. That is not devotional activity. Devotional activity is different from pious activity. By pious activities you can get material, so-called happiness, janmaisvarya-sruta-sri [SB 1.8.26].
You can get birth in very nice family, rich family, brahmana family, janma; and you can get immense wealth, born with silver spoon; and aisvarya-sruta, education, nice education, material education; and sri, beauty. Generally, you will find in aristocratic family, rich family, they are very beautiful, they have got education, they have got wealth and good family, aristocratic family. So these are result of pious activities.
