I applaud any way you choose to enrich the lives of others, and restore some sanity to what might be an otherwise daunting and crazy time of year, especially in our global and local political climates.
If you are local, and so inclined, I am collecting new, unwrapped toys for children of all ages for the families in the community of where my son goes to school. A few decks of cards, a science book, a set of construction blocks, an easy reader set, coloring books and crayons, toy cars, a huggable stuffed toy, a hiking journal, a kid's yoga mat - any thing you have or could pick up easily at a minimal expense would be so gratefully appreciated.
You may bring them to any of the classes that I teach around the county (no need to ship anything from out of town please) and I will bring them en masse to the donation box at our school. We have 20 families on our holiday list to whome we'd like to bring a little extra cheer.
In Sanskrit Seva means selfless service. There are a number of words that are synonymous with charity or giving or the act of that. Here is a short list I found:
Atisarjana: the act of giving away something or making a donation.
satkriyā: a good action, charity, virtue
vara: Charity, alms
āmiṣadāna: gifts of material sthigns (in buddhist philosophy)
but my favorite so far is paropakāra: assisting others, benevolence, charity
