Here everyone is engaged in fruitive activities, karma. Karma in this life and karma in the next life also. So performing great sacrifices, giving in charity, pious activities, they are also karma. They are meant for giving opportunity in the next life, a position in the heavenly planet or similar other higher planetary system where the standard of living is very, very comfortable, thousands and thousands times better than the standard of life in this planet. But that is also karma.
