We shouldn't think we can stay in samasara and be saving mother sentients being if we have not attained anutpattika-dharma-kṣānti yet. We should go to Amitabha Pureland so that we can learn from Buddha Amitabha.

Just before dying, let go of everything, and have confidence in going to the Pureland. This confidence and aspiration can suppress our karma.

Impure land, i.e. samsara, is caused by self-interest, ego.

Pureland, is the opposite.

We first need to contemplate that all sentient beings have been our mothers in different lives.

Then we need to make aspiration to save all sentient beings.

There is a differences in stage. Starting from contemplation, then aspiration, BUT still unable to be useful in helping others due to our imperfections
