Parents

Mother, Mother

You are dearer than other

Father, Father

You are superior to other
Though you don’t become famous

You both can die for us

For us you are incarnation of god and first school

It is you who teach us in every moment to be graceful

We the children learn to walk catching your finger

It is you who always save us from danger

There is heaven and world at your feet

No other can take your seat

We the children want only blessings from you

You are everything for us from all point of view.

MYSTERIOUS FOREST

THERE IS A FOREST

WHERE NOTHING IS IN REST

WHEN WE TOUCH LEAF

ANIMALS BECOME DEAF

IN SPITE OF DOG, LIONS BARK

IN DAY IT IS ALWAYS DARK

THE WATERS ARE OF COLOR RED

BY RABBIT, TIGERS ARE AFRAID

NO SOUND COMES OUT THOUGH THEY HAVE MOUTH

NO ONE KNOWS WHAT IS THE MYSTERY ABOUT?

MY MOTHERLAND

Warriors saved its sovereignty

by the use of knife

this is my motherland,

Lovable than my life

In tradition, cast, culture, language

there is diversity

Despite of these differences

there is strong unity

Here people shows such love

that it can even uproot hostility

Throughout the world

It has spread its identity

My motherland is full of

Lowland, valley and Doon

For us these are

a great boon

My motherland is

Superior to heaven

Of different cast sub cast

Its a common garden

Before her, she has let

no enemy to stand

Thus, I proud to be son

Of my motherland.

FESTIVALS AND TRADITIONS

Holi is a festival of Hinduism
Any people can participate of Buddhism
No Islam or Christianity will be separated
Because the equality is highly exaggerated

Every country has physical and cultural diversity
So we are challenged to maintain unity
Every castes have customs and traditions
But we should maintain unity in every variations

Buddha taught us non-violence
So we should always pray him with great silence
Parents are our god
So with them we should not do any kind of fraud

Every festivals should be celebrated with great devotion
Because they are important occasions
Festivals are observed for life long and beauty
But not to kill the god gifted humanity

Hindu, Muslim, Buddhism, Christian
Above all, we are human
Don't judge people on the basis of their caste
Because it's only good deed that counts and lasts

---Vijay Yadav

Poem

I saw a bird...

It was the time of evening
when I saw a bird singing

She was sitting on a lawn
having got her wonderful eyes glown

Her head seemed to be brown
because of a beautiful and shiny crown

Near to me there was a spring
where she was continuously seeing

I wondered for sometime what was there
but soon I realised her friend was being stared

Suddenly, she started to sing in a sweet voice
then I thought she must be the nature's special choice

After sometime she flew to her way
giving me the freshness of whole day

I waited for her many seasons
and finally a bird came who seemed just like the previous pigeon
