Idea 2: Choose a particular time/instant in your daily life to remember him
I remember Ummi bai Merali saying once in a lecture that when we come home from somewhere and as we stand in the doorway while waiting for the door to be unlocked, why not face kibla and say Salaam to our Imam at that moment? Hopefully then this should become a habit, and we would be remembering him at least at those point in our day!
The other day I saw the coolest thing which reminded me of that. I rang the bell at someone’s house and heard some recitation through the door. When I asked what it was, she said her doorbell was not a ring as such, but recited “Ya Mahdi” when pressed! How awesome is that? That way you remember him even when someone else comes home
P.S. Apparently the doorbell is available in Iran!
