Nothing

Rebbe Nachman once told me "When things are very bad, make yourself into nothing. Uhu as es iz shoin gar schlecht, iz min zich gar m'vatel."

I asked him: "How does one make himself into nothing!"

He replied: "You close your mouth and eyes - and you are like nothing! Me far-macht das moil, uhu die oigen, iz bitul."

We can gain valuable insight from these words.

Sometimes you may feel overwhelmed by the Evil Inclination. You are confused by evil thoughts and very disturbed, finding it impossible to overcome.

You must then make yourself like nothing, you no longer exist, your eyes and mouth are closed. Every thought is banished. Your mind ceases to exist. You have nullified yourself completely before G-d.
