The pain of losing someone can never be compensated no matter what. However these few words of sympathy will at least ease the burden of pain off your loved ones who have lost someone close to them.

I am really at loss of words
I don't know how to react in this situation and time
Just want to say that this too shall be gone with time
You need to stay strong for your family
You need to stay strong for him
May his soul rest in peace!

I felt my heart broke into pieces when I heard about the sudden death of your beloved father. He was a great person. He will truly be missed.

Nothing can make you feel better at this time
But you need to stay strong and move on
I know it's really tough for you
But you have to do it for your family
This too shall pass in life
May your father's soul rest in peace!

It takes time to get over the pain. But the knowledge that he's in a better place now should help you get over the pain a little sooner.

The pain of losing a parent can't be described in words
He was a man of wisdom
He was so complete in life
May his soul rest in peace
And may all your sorrows cease
Stay strong as we are with you in this grief!
