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.
Even after all this time the sun never says to the Earth, “You owe me.” Look what happens with a love like that, it lights the whole sky.
We need to be aware of our own selves, our body, our breath, our mind, how the mind works. Become confident of who you are.
Everything is the Supreme Being, which is Existence – consciousness - bliss, and ‘I am That’. By constantly cultivating this pure thought, get rid of impure thoughts. Then discarding even that thought and always inhering in the state of fullness, you will become the non-dual and undifferentiated Supreme Being and attain liberation.
