by natural conspiration and agreement, and by substantial union,
or, reduction of all substances into one.

XXXV. Fit and accommodate thyself to that estate and to those occurrences,
which by the destinies have been annexed unto thee; and love
those men whom thy fate it is to live with; but love them truly.
An instrument, a tool, an utensil, whatsoever it be, if it be fit
for the purpose it was made for, it is as it should be though
he perchance that made and fitted it, be out of sight and gone.
But in things natural, that power which hath framed and fitted them,
is and abideth within them still: for which reason she ought

all in all doth enjoy his happiness.

XXXVI. What things soever are not within the proper power
and jurisdiction of thine own will either to compass or avoid,
if thou shalt propose unto thyself any of those things
as either good, or evil; it must needs be that according
as thou shalt either fall into that which thou dost think evil,
or miss of that which thou dost think good, so wilt thou be ready
both to complain of the Gods, and to hate those men, who either
shall be so indeed, or shall by thee be suspected as the cause
either of thy missing of the one, or falling into the other.
And indeed we must needs commit many evils, if we incline to any
of these things, more or less, with an opinion of any difference.
But if we mind and fancy those things only, as good and bad,
which wholly depend of our own wills, there is no more occasion
