Hi there! Dharani is a word that comes from an ancient language called Sanskrit. In that language, dharani means something that helps you remember something else.
Imagine you have a special toy that always reminds you of your best friend. That toy would be like a dharani for you, because it helps you remember your friend even when they're not around.
In ancient times, people developed different types of dharanis to help them remember important things like prayers or teachings. Some dharanis were like special words or sounds that were repeated over and over again, almost like a song, until they sank deep into a person's memory.
Other dharanis were visual, like pictures that illustrated important stories or messages. Sometimes people would even make physical objects like talismans or amulets to act as dharanis, because they believed these objects would help them remember good luck or protection.
Now, even though many of these practices are very old, some people still use dharanis today as part of their meditation or spiritual practices. It's kind of like having a special tool to help you focus your mind and remember the things that matter most.
