It’s all a question of motivation. if you help yourself so you can be better assist to others – it’s a good thing.
But also, we should be aware that we might want to help other people – by telling them about religion, by changing or affecting their lives. But unless we have changed the root cause of ignorance in our own lives, we are likely to be acting out of ignorance, or making things worse.
For that reason, the best thing we can do for other people is to hold them dear, but to make private effort in study and meditation to break free of our own problems first.
