“I haven’t seen my father for 20 years. I wonder if it is due to the karma, or is it good or not good.” If he did something wrong, you forgive him. Because our real Father is not even him. Everything works out just fine. Whatever happens, happens. It’s not your fault; it’s not his fault. Just the working of karma. Sometimes, he has only affinity with you for two days or two years or five years, and the affinity’s finished, he’s gone. Sometimes it’s good to forgive. It feels good. Otherwise, there’s a knot in there all the time if you don’t open it. Maybe just have a look at him, and talk to him. You don’t have to always see him, but no need to hate the person. At least, he is an excuse for you to come into this world, and then you meet spiritual practice.
