Harmony

Harmony is the essence of Tagore's view of the world.. He has perceived harmony in the , "..marvellous quality of complex inter-relationships maintaining a perfect co-ordination of functions." This concept of harmony can be defined as a process of continuous synchronization among the different aspects of the natural world.
"The same stream of life that runs through my veins night and day runs through the
world and dances in rhythmic measures.
It is the same life that shoots in joy through the dust of the earth in numberless blades of
grass and breaks into tumultuous waves of leaves and flowers.
It is the same life that is rocked in the ocean-cradle of birth and of death, in ebb and in
flow"
The natural world is in a constant flux, a ceaseless change, like the movement of the waves, where appearance of the one leads to the disappearance of the other, rising and falling in a continuous rhythm.
This cyclic process the Brahmanda Purana mentioned in its theory of creation as 'Sarga or primary creation and pratisarga .which includes dissolution and recreation.
Interestingly the harmony found in the natural world seems to have been permeated in the human thought process or how else can one explain the Stoic 'apocatastasis' so similar to the Puranic cosmology!it explained the universe as a living being, which was born, lived its allotted span of time and died only to reproduce itself? The Stoic s believed that the universe was animated by vital breath that burned through its entire extant vibrating all its parts that were interconnected.
"This universe, which is the same for all, has not been made by any god or man, but it always has been is, and will be -- an ever-living fire, kindling itself by regular measures and going out by regular measures" commented Heraclitus the Greek philosopher and Tagore expressed all these philosophical findings by saying

আছে দুঃখ, আছে মৃত্যু, বিরহদহন লাগে।
তবুও শান্তি, তবু আনন্দ, তবু অনন্ত জাগে ॥
তবু প্রাণ নিত্যধারা, হাসে সূর্য চন্দ্র তারা,
বসন্ত নিকুঞ্জে আসে বিচিত্র রাগে ॥
তরঙ্গ মিলায়ে যায় তরঙ্গ উঠে,
কুসুম ঝরিয়া পড়ে কুসুম ফুটে।
নাহি ক্ষয়, নাহি শেষ, নাহি নাহি দৈন্যলেশ--
সেই পূর্ণতার পায়ে মন স্থান মাগে ॥

Aachhe dukhyo, aachhe mrityu, birohdahan laage
Tabuo shanti, tabuo aananda, tabuo ananta jaage
Tahu pran nityodhara, hase suryo chandra tara,
Basanta nikunje aase bichitra rage
Taranga milaye jaay taranga uthe,
Kusum jharia pare kusum phute
Nahi kshay, nahi shesh, nahi nahi dainyaleshe
Sei purnatar paye man sthan mage

"There is sorrow, death there is:
There is the pang of separation
Yet is there peace,
There is joy,
There is the call of the infinite within:
there is within us the eternal flow of life,
the radiant beaming sun,the smiling moon and stars
Yet spring, arrives at our doorstep\
bringing to bowers,
a wondrous spray of shades and colours.
As the tide falls so also the tide rises
When a flower droops and falls another blooms...
There is neither loss nor an end, no, not even weariness
At that altar of abundance, my heart seeks its abode.
