Why is monsoon considered a unifying bond?

(i) The Himalayas protect the subcontinent from extremely cold winds
from Central Asia. This enables northern India to have uniformly higher
temperature when compared to other areas on the same latitude.
(ii) The Peninsular plateau under the influence of the sea from three sides
has moderate temperatures.
(iii) The seasonal alternation of wind systems and the associated weather
conditions provide a rhythmic cycle of seasons’
(iv) Even the uncertainties of rain and uneven distribution are very typical
of the monsoon.
(v) The Indian landscape, its animals and plant life, its entire agricultural
calendar and the life of the people including their festivities revolve
around this Phenomenon.
(vi) These monsoon winds bind the whole country by providing water to get
the agricultural activities in motion. The river valleys which carry this
water also unite as a single river valley unit.
