How will you meditate? To meditate you must think about God. But God is infinite and eternal, so how will you be able to imagine this? You can't, it is beyond the mind.
So think of God as all-pervading effulgence. Try to bring before your mind's eye a picture of an ocean of infinite, all-pervading effulgence, which is God. A shoreless, bottomless ocean.
But if this ocean of effulgence is infinite and all-pervading, where will you be? What will your position be? If you imagine this ocean in front of you, then it is not infinite. So try to bring before your mind's eye this infinite ocean of effulgence, and imagine yourself in it. You are in the midst of this infinite ocean of effulgence. Try to picture this when you meditate.
Satara, DH p62-63
