By emptying your mind, you get rid of all things, including God, for a while. Since you cleared God out of your head, you cleared the Holy Spirit out of your head. As a result, you have no protection against evil.
Indeed. In fact, the traditional Catholic remedy to defeat vices is to crowd out the ideas and desires fostered by those sinful habits by the influx of new, holy ideas and desires. For example, watch
this classic video of Ven. Fulton J. Sheen starting from the 16th minute mark, but the whole video is frankly very interesting in itself.
But let us go back to the OP. G.K. Chesterton made this observation about the differences between Buddhism and Christianity:
Even when I thought, with most other well-informed, though unscholarly, people, that Buddhism and Christianity were alike, there was one thing about them that always perplexed me; I mean the startling difference in their type of religious art. I do not mean in its technical style of representation, but in the things that it was manifestly meant to represent. No two ideals could be more opposite than a Christian saint in a Gothic cathedral and a Buddhist saint in a Chinese temple. The opposition exists at every point; but perhaps the shortest statement of it is that the Buddhist saint always has his eyes shut, while the Christian saint always has them very wide open. The Buddhist saint has a sleek and harmonious body, but his eyes are heavy and sealed with sleep. The mediaeval saint’s body is wasted to its crazy bones, but his eyes are frightfully alive. There cannot be any real community of spirit between forces that produced symbols so different as that. Granted that both images are extravagances, are perversions of the pure creed, it must be a real divergence which could produce such opposite extravagances. The Buddhist is looking with a peculiar intentness inwards. The Christian is staring with a frantic intentness outwards. If we follow that clue steadily we shall find some interesting things.
Orthodoxy, Chapter 8: The Romance of Orthodoxy
Now it may seem that G.K. Chesterton is wrong about this, because we have read so many recommendations from saints to look inward for God; indeed, Jesus Himself said:
[BIBLEDRB]Luke 17:21[/BIBLEDRB]
But that is the thing: we Christians look inside of us
not to find ourselves but God. Indeed, when we are called to look at ourselves, we are often told so so we can distrust ourselves, and therefore we look for the One we can trust that is outside ourselves—indeed, outside of creation!—by looking inside ourselves.
