If you have known yourself, you have known everything else. Know that, by knowing which, you will know everything else. The Bible says, “Seek that kingdom within you.” Once you have found that, then everything else will be automatically added unto you; you don’t have to go looking for things outside; they will all come to you.
Choose your own way, to suit your own taste, temperament and capacity. There’s no need to criticise or condemn those who follow a different path. Spiritual hunger is the same in all – the ‘food’ to satisfy their hunger may vary.
Keep your body as clean as possible, your mind as clear as possible. That’s all you need. And do it in any way you can, in your own way. It doesn’t matter. And then you’ll be useful.
