What is the soothsayer's plan in Act 2 Scene 4 of Julius Caesar?

The Soothsayer informs Portia that he will warn Caesar to look out for himself,

"That I have, lady. If it will please Caesar

To be so good to Caesar as to hear me,

I shall beseech him to befriend himself."

He tells Portia that he is not certain what things will happen but there are many bad things that can happen. He says there are plenty of bureaucrats that would gladly suffocate a feeble man. The Soothsayer wants to find an open space where he can get close enough to speak with Caesar,

"The throng that follows Caesar at the heels,

Of senators, of praetors, common suitors,

Will crowd a feeble man almost to death.

I’ll get me to a place more void, and there

Speak to great Caesar as he comes along."
