Onset of Monsoon by the end of ज्येष्ठ and शनि जयंती is not co-incidence but finest example of dharma based living.

Monsoon : Vata Prakop

Each dosha sees fluctuation based on season. Fluctuation is divided into three states.

१) छाया २) प्रकोप ३) शमन

Chaya means slight increase of Dosha in its own place.  It produces dislike against the things that would cause further increase of particular Dosha.  It is a self defense mechanism of the body to avoid further increase of Dosha, which may lead to disease. 22

Kopa – suggests further increase of Dosha and overflow of increased Dosha into other body channels. It causes appearance of symptoms of increased Dosha, leading to onset of disease process. The premonitory symptoms of the disease can be observed at this stage.

Shama means normalcy. Restoration / decrease of increased Dosha to its normal levels.

Fluctuation of Dosha in different seasons –

Dosha  Chaya  Prakopa  Prasama
 Vata Grisma (summer) Varsha (rainy) Sharat (Autumn)
Pitta Varsha (rainy) Sharat (Autumn) Hemanta (early winter)
Kapha Shishira (winter) Vasanta (spring) Grishma (summer)

जेठ is the month when वात छाया starts turning into वात प्रकोप. This is also a month when we worship Bhagwan Shani.

शनि भगवान & Blame games
Shani Bhagwan is ruler of our minds. His Vahan is Crow.
Crow or कौआ = चलद्रष्टि = wavering sight = The one who cannot focus on one task = wavering mind = वात वृध्धि = वात प्रकोप
wavering mind = Half baked actions/decisions = chances of failures
शनि पनोती = You will more than likely under वात प्रकोप with wavering mind.
If you worship Shani bhagwan and lucky to get his blessings, you will be able to control your mind. He controls Crow type minds.
In this picture, you also see चूहा.
चूहा = चंचल चित्त = Wavering mind (Ganesh bhagwan worship too can help controlling Vata effects on mind)
The Blaming Phenomenon

Saturn weakens energy and enthusiasm for the common life in order to highlight the extraordinary, the very depths of the soul.

Sometimes it is a disease, or sometimes another crisis that by extracting us from our normal activities can act as an opening to a much fuller life, if we can refrain from trying to suppress or avoid the reevaluations into which it will lead us. Sometimes it is depression, which is also ruled by Saturn.

Those who work through their depression will find themselves emerging into deep contemplation, as King Vikrama did. His misery, once digested, emerged from him as song, as it should for everyone who loves the Lord.

The king did not grumble over his sufferings, or whine about how everyone had it better than he, or had it in for him. Instead of blaming other people, he blamed his own karmas.

One of the least useful of human attitudes toward the cosmos is the “blaming phenomenon,” in which everything except one’s own self is held responsible for one’s woes.

Saturn is often the most blamed; in the words of my Jyotish guru, “Poor Saturn. He is crying because everyone blames him; but what can he do? It is part of his portfolio to make people experience Reality.”
