Your Shul Has A Ner Tamid
Right?
Your home should too!
Ideally, olive oil.
Light it once and keep adding oil as necessary.
Easy avoda which burns away the impurities of this compromised world.
If not feasible, make sure an electric light is always on somewhere in the house.
Like the one in shul (unless the community is enlightened…).
Absolute minimum, get a set of Zohar.
Light Up Your Yiddishkeit!
