SONNET-116 or... what about love?

came across this sonnet first time a lonnnnnnnnnnnnnnnnng back, i think in 2006/07 when i bought the collection in lamington road. but then gave it only a little thought; and later, left reading it altogether. that english was very hard and tough on me.

now thought of bringing it in here. soooo...here it is...

SONNET-116

Let me not to the marriage of true minds

Admit impediments. Love is not love

Which alters when it alteration finds,

Or bends with the remover to remove:

O no! It is an ever-fixèd mark

That looks on tempests and is never shaken;

It is the star to every wandering bark,

Whose worth's unknown, although his height be taken.

Love's not Time's fool, though rosy lips and cheeks

Within his bending sickle's compass come;

Love alters not with his brief hours and weeks,

But bears it out even to the edge of doom.

If this be error and upon me proved,

I never writ, nor no man ever loved.

–William Shakespeare

and how do i understand these lines!?

Let me not to the marriage of true minds

Admit impediments.

when 2 love each other sincerely, no reason can stop them from getting together.

Love is not love

Which alters when it alteration finds,

Or bends with the remover to remove:

it is not love if it changes as the physical appearance with aging, financial status or something like that change;  nor is it love when it finds a better opportunity in a tempting situation.

O no; it is an ever-fixed mark, 

That looks on tempests, and is never shaken;

It is the star to every wandering bark,

Whose worth's unknown, although his height be taken.

true love is fixed like a point/a beacon beaten by tornadoes and tempests of disturbing circumstances that may seem to destroy everything on their path.

it is like a polestar for a boat that had lost its direction in high-seas. it's the solace for a life which seems to go adrift and wander aimlessly as the time progresses.

the height of the polestar from the horizons is easy to measure; but the value of getting direction, guiding boat into safety, thereby saving life is priceless.

Love's not Time's fool, though rosy lips and cheeks

Within his bending sickle's compass come;

as time passes, true love doesnot change, though physical beauty of the beloved fades away due to aging.

Love alters not with his brief hours and weeks,

But bears it out even to the edge of doom.

love does not change in days/weeks/months/years. it simply lasts till the end of life.

If this be error and upon me proved,

I never writ, nor no man ever loved.

if these claims are proved wrong, then....it's like, whatever i have written is just nothing and, no one has ever experienced the gifted feeling of true love.
