O YOU whom I often and silently come where you are, that I may be with you;
As I walk by your side, or sit near, or remain in the same room with you,
Little you know the subtle electric fire that for your sake is playing within me.

“You will hardly know who I am or what I mean,
But I shall be good health to you nevertheless,
And filter and fibre your blood.

Failing to fetch me at first keep encouraged,
Missing me one place search another,
I stop somewhere waiting for you.”

Are you the new person drawn toward me?
To begin with, take warning - I am surely far different from what you suppose;
Do you suppose you will find in me your ideal?
Do you think it so easy to have me become your lover?
Do you think the friendship of me would be unalloy’d satisfaction?
Do you think I am trusty and faithful?
Do you see no further than this façade—this smooth and tolerant manner of me?
Do you suppose yourself advancing on real ground toward a real heroic man?
Have you no thought, O dreamer, that it may be all maya, illusion?
