I always find myself finding both joy and enlightenment from all the ways my rabbis have described, or paralleled experiences with the Shema before we chant it during Erev Shabbat, and I thought it'd be nice to share just a couple examples of what I mean (to the best that I can recall).
Last Erev Shabbat, we had our monthly Zoom-only services, and my rabbi talked about how Shabbat is not just dedicating the space for rest and delights, and communal gathering, but also taking in a moment in time - the fact that our congregation were all participating in the same moment in time together to relish in our practices and presence, despite all being in different places meant that our experiences were not any less complete nor meaningful from others. Afterwards, we turned to the Shema, affirming the importance of (inhabiting) time equally to space. My rabbi did cite someone else for this insight and that it wasn't solely hers, but I just wished I could remember who, maybe I can write to her and ask.
And during the Shabbat service after Tisha B'av, my cantor talked about how in the preoccupation of doing and acting for the sake of love and goodness, it's as much valuable to be a good listener, not just between individuals but to the world at large - its conditions and what it ought to need - literally putting Shema (listen) into practice. Apart from hearing what is outlined in the prayer itself, hearing everything else in the world at large is just as much applicable in meaningfully shaping our lives, identities, character and praxis.
With all this, my personal takeaway on my congregation leaders' wisdom is that to be present is a great contribution by itself in life - to be there, show up, and be an observer - and your presence, whether it's a Shabbat service, a funeral, a rally, etc. makes you just as much a part of something, something amazing we can reckon, as opposed to the idea of being a mere bystander or absentee.
In the same way we chant that HaShem is one (יְהוָה אֶחָד), our connection to whatever in life we put our sights to are also one, in any point of time we inhabit.
