On your attendance, my lord, here

Viola
On your attendance, my lord, here.
Orsino, to Curio and Attendants
Stand you awhile aloof.—Cesario,
Thou know'st no less but all. I have unclasped
To thee the book even of my secret soul.
Therefore, good youth, address thy gait unto her.
Be not denied access. Stand at her doors
And tell them, there thy fixèd foot shall grow
Till thou have audience.
Viola
Sure, my noble lord,
If she be so abandoned to her sorrow
As it is spoke, she never will admit me.
Orsino
Be clamorous and leap all civil bounds
Rather than make unprofited return.
Viola
Say I do speak with her, my lord, what then?
Orsino
O, then unfold the passion of my love.
Surprise her with discourse of my dear faith.
It shall become thee well to act my woes.
She will attend it better in thy youth
Than in a nuncio's of more grave aspect.
Viola
I think not so, my lord.
Orsino
Dear lad, believe it;
For they shall yet belie thy happy years
That say thou art a man. Diana's lip
Is not more smooth and rubious, thy small pipe
Is as the maiden's organ, shrill and sound,
And all is semblative a womans part.
I know thy constellation is right apt
For this affair.—Some four or five attend him,
All, if you will, for I myself am best
When least in company.—Prosper well in this
And thou shalt live as freely as thy lord,
To call his fortunes thine.
Viola
I'll do my best
To woo your lady.  Aside.  Yet a barful strife!
Whoe'er I woo, myself would be his wife.
