nothing

To be humble let us listen to the revelation of the Holy Ghost which is infallible. "Behold you are nothing, and your work is of that which hath no being." [Isa. xli, 24] But who is really convinced of his own nothingness?
It is for this reason that in holy Scripture it is said: "Every man is a liar." [Ps. cxv, 2] For there is no man who from time to time does not entertain some incredible self-esteem, and form some false opinion as to his being, or having, or achieving something more than is possible to his own nothingness.
To know what our body is in reality, it will suffice for us to look into the grave, for, from what we see there, we must inevitably conclude that as it is with those decayed bodies, so it will soon be with us. And with this reflection I must say to myself: "Why is earth and ashes proud?" [Ecclus x, 9] "Behold the glory of man! for his glory is dung and worms; today he is lifted up, and tomorrow he shall not be found, because he is returned into his earth, and his thought is come to nothing." [1 Mach. ii, 62, 63]
O my soul, without going further to seek truth, enter in thought into the heart of thy dwelling which is thy body! "Go in and shut thyself up in the midst of thy house." [Ezek. iii, 24] Go in and look well around thee, and thou shalt find nothing but corruption. "Go into the clay and tread." [Nahum iii, 14] Wherever thou turnest thou wilt see nothing but putrefaction oozing forth.
