The poem becomes much more grounded and down-to-earth in the description of the next way to love. As the speaker explains, she loves her beloved "to the level of everyday's / most quiet need." This is a reminder that, even though she loves him with a passionate, abstract intensity (see lines 2-4), she also loves him in a regular, day-to-day way.
Even though it's not directly described, we get a sense of everyday domestic living here – the reality of wanting to be with someone all the time in a low-stakes kind of way. This is a "married-and-hanging-out-watching-TV-on-the-couch-each-night" kind of love, instead of a "Romeo-and-Juliet-are-going-to-die-tomorrow" kind.
It's important, however, that this doesn't mean the love is any less significant. The everyday "need" for love may be "quiet," but it's definitely there.
The speaker completes the description of this everyday love with two images of light: "by sun and candle-light." Basically, this is just a way of saying "in the day and at night," but it also reminds us that the lovers are looking at each other all the time – and that the speaker here loves her beloved no matter what light she sees him in.
If you're counting, this everyday love is the second of the "ways" of loving that the speaker lists.
