In plain words
Yet it is on what we do not see, on what does not appear to us to move, that these second hands and the minute hand depend, and so they were needed; if this hour hand itself were not there, the minute hand and the second hand would be of no use to us. In the same way, our gross body is doing all kinds of karma. This is like the second hand. Only when this does many kinds of sacred karma does this subtle form, the mind, come to a certain sacredness. Only when this subtle mind thinks many sacred thoughts does it attain the state of the Ātma, called the causal body. The gross body and the subtle mind came into being only for the sake of the causal body; without the causal body itself, this gross and subtle are of no use to us. So when we keep this cause as our goal and lead the gross and the subtle onto a sacred path, we have the chance to reach easily the place of the Ātma, which is the causal place. This, merging in one's own reflection, cannot be called riddance. To go back and join the place it came from can only be called merging; it cannot be called fulfilment, nor can it be called riddance. Here is another small example of this.
The Jñāna of Experience Is More Essential Than Knowledge of the Śāstras
Now, we know the ocean is very vast. But on another side we see water filling a tank. On yet another side we see it as a great stream, in a confused state. Then in our house we see water in a few taps. We see water in the well. What is the source of all these waters? That very ocean. But when we inquire how the ocean water comes to these tanks and to the streams, that itself shows the right example. The sun's rays fall on this ocean, and through that the water turns itself into vapour, takes form as clouds, then falls as rain, sets out as rivulets, comes as a stream and joins the tanks. So these streams flow on very grandly and merge back into the ocean itself. Taking this as the example, this ocean itself is grace. When the sun's rays, which are the rays of our intellect, are brought onto this ocean called grace, they turn into vapour in one form, called a kind of feeling.
