Please allow me to preface the question because, as a foreigner who did not grow up with Sanatana Dharma, my practice probably differs from yours.
All of my life when traveling statues, stones, a shrine, and other objects specific to the culture of the area have made their way to me. I never set out to buy, for example, a specific statue. I would simply browse a local vendor and suddenly something would call out to me. Several pieces were given to me at a crucial juncture in my life. These are from places all over the word, but, for me, they all speak to different aspects of the divine—which I see as One.
So, I have recently moved and I started putting these pieces on a desk in the corner. Though I did not intend for it to happen as I was laying them out, I realized that I was intuitive building a kind of altar. For the week or two I have been in this new home I have kept up the altar and have certainly felt its effectiveness.
However, the surface on which everything sits (and in which my incense and other tools are kept) is a desk. My friend and neighbour needs a desk and I do not require this particular piece of furniture to be the piece of furniture on which the objects are aligned.
I have been looking at buying a mandir, but they clearly are meant to sit on top of another surface—otherwise everything would be too low to the ground. Is there a name for the table, shelf, or surface on which a home temple sits? What sort of thing should I be looking for? A simple end table from a large "big-box store" feels inappropriate.
