Sand Castles

It is a series of 5-7-5 poem (haiku)...

         1
Against the fierce waves
Sand castles remain slaves..
Tides melt them away

         2
Wish in time will stand..
Hopes the sea could understand.
weak as they may be..

         3
The sunset glowed bright..
Like it welcomes the dark night..
Castles are no more..

         4
Deep in sea they rest..
but remembered they are blessed..
Once, they were onshore
