We have said that Vishu 8 or the Sun’s entry into the eighth degree of sidereal Aries, is the time for the farmers to sow.
Vishu or the solar ingress into Aries, is celebrated all over Kerala. This is the dawn of a good era, as it marks the end of the hot seasons of Kumbha ( Aquarius ) and Meena ( Pisces ). Temperature touching 43 degrees is disconcerting. Vishu is the heralder of the two monsoons, the South West and the North East.
The Vedic Calender is astro-meteorological and the farmers know when to sow and when to reap. So the best time to sow is in Medam or Mesha or Aries. Anything planted after this date will fructify, as the Edava Pathi or the South West Moon takes over in June and the Thula Varsham or the North East Monsoon takes over in Oct-Nov.
In traditional farming, plants and trees need watering on alternative days. Now both monsoons ensure that plants and trees will be watered by Nature !. Hence the green landscape engineering done by Nature makes Kerala beauteous !
When the Sun reaches its maximum declination at 23 degrees 27 mins South, at the Tropic of Capricorn, ( the end of Dakshinayana ), the Indian Ocearn becomes hot & the northern places of the Indian subcontinent becomes cool. Then we find the phenomenon of cool winds condensing to form clouds, picking up moisture laden winds from the Bay of Bengal, sweeping down on the Himalayas and the Indo Gangetic plains and then pouring over peninsular India. Kerala also gets these rains and hence the South West Monsoon which ends in September is replaced by the North East Monsoon and this rainy season or watering by Nature continues till Dhanus, the 15th of December ! Hence the tourists find Kerala enchanting, because of the greeen landscape architecture effectuated by Mother Nature !
India is an agrarian economy, dependent heavily on the monsoons. In 1895, the rains never came and India experienced drought and famine. The monsoons can also be destructive. Trees are uprooted, cables smashed, houses destroyed as a result of poor infrastructure. In 2008, our paddy fields were flooded due to heavy rains and the nearby inhabitants had to be evacuated. Despite its potential for destruction, monsoons are generally welcomed, as it liberate the natives from the blistering heat of Kumbha (Aquarius ) and Meena ( Pisces ).
Vishu marks the beginning of Vasanta Rithu, the first of the six seasons.
Farmers in Kerala say that
the seeds sown on Aswathi Jnattuvela ( the Sun’s transit of the first 13 degrees of Aries )
and mango seeds sown on Bharani Jnattuvela ( the Suns’s transit of the constellation of Bharani )
will fructify.
The best time for planting cocounut trees is on Patham Udayam, the Tenth Rising of the Sun, when Sun enters the tenth degree of Aries.
So Vishu is an agricultural festival, based on the Wisdom of the Heavens and not a religious festival !
