Just a quick observation, please don't write in capital letters. Besides being harder to read, it denotes shouting, which detracts from the essence of the poem.
Cheers Jx

Just lazy :) - wow this has got some real passion, and you've made a flying start..just on the emphasis, while getting your point across - can be FUNDAMENTAL to a poem, you don't have to do upper case all the time, if you check out some of the poets on here, you'll see they do occasionally use CAPS for emphasis, maybe because it's easier than figuring out the html formatting, but then you can also use space and silence etc. to build up to the next line.

Good start, well done,

Cheers.

They are right about having a good start here. Just a couple of crits. You need an [s] on the end of complete[s] I think the word that you are looking for is while, not when and maybe [lessens] not lessons. other than that, I like the passion with which this has been written. ~ Geezer.

I've taken the liberty of uncapping this for you (a simple task in Word, just select and press Shift F3, once for uncapped, twice for caps at start of sentence, 3times for cap initial letter of each word). You can also use the Advanced Formatting option to get Bold (Ctrl B) or Italics Ctrl I.
 

For This Cause

Mercy and ferry, shun the teary lane
hand in hand board the joyous train
side by side fight the unseen fight
together with you makes the journey easy

Dear! How pleasant it is
to tread this scary life with ease
you have been blessed with peace
to have the piece that complete your being

Let your soul bid loneliness farewell
now that you’ve had a sip from love’s well
you have your third and forth hand
to confidently pursue ten thousand
two are better than one is what they say,
enjoy the moment of togetherness when it last

When you drive in the street of thoughts
one may crash but two will stand on the loft
when you rest in the arms of fierce cold
one may shiver but two will hotness unfold

Fixing this puzzle always lessons the hustle
love helps you thresh the ugly hurdle
so enjoy the fellowship of togetherness
for together, you can fulfill your dreams….
