Every time you have the lobha mind, again and again, if you don’t know, then attachment grows stronger and stronger.
Every time you meet the same people, you use the same things, if you don’t know that lobha is happening, then attachment grows bigger and bigger. Like the hot shower – every day you use it, but you don’t know with what mind you’re taking the shower. You think that you’re mindful! There’s attachment there, and you let the attachment continue.
Defilements can happen anywhere – defilements have a chance to arise through any of the 6 sense doors. If defilements don’t get weaker, then wisdom cannot grow. So, you have to be aware all the time.
