The speaker describes a small, settled life and then, at the end, invites you into it. They say they neither come nor go, and they stay put without any "flow," which suggests a life that is still rather than restless. What they have is modest: shade, a drink, some food, and enough time to think. The garden is "careless," meaning untidy and unforced, yet it still gives flowers, and there is "no burden" in tending it.
The flowers are shared in two ways. Some go to the speaker's gods, and some stay on the table where, as the speaker puts it, poems "form pods," like seeds growing quietly. In the last stanza the mood turns outward. The speaker welcomes a visitor to bring poems and songs, sing together, and "forgive all wrongs."
Overall the poem feels calm, content, and gentle. It treats simplicity as a kind of wealth, and it suggests that peace is something to be shared rather than kept alone.
