It is true, we just chant Hare Kṛṣṇa, but what does that mean? How do we apply that as a conditioned soul? That we have to understand. We do chant, that is our main focus, yes. But since we are not satisfied with that, therefore there are other processes.

The whole mood of the vrata is that it’s about Kṛṣṇa, but here it’s just all about their inconvenience of fasting. So better they not fast. They will get more spiritual benefit.

For Kṛṣṇa, spending time with the devotees - that is what is important. Just getting things done, He is already doing that as Paramātmā, and He is not with the devotees, that's why it is considered a lower level.
