Looking at Shirshasana mentioned in Uttara ( north) Kanda( land/chapter) in Ramayana.
A citizen of Rama’s kingdom cannot make sense of Rama’s poor treatment of his wife Sita.
It saddens him as Rama is known for his Adarsha (ideal and moral) and to understand why he contemplates by going upside down.
As the world makes little sense straight side up!
In art I think it was Braque who said during the nazi occupation and subsequent war that the ‘real’ world seemed so completely unreal during the time. Which is why artists developed dispassion towards representing ‘reality’ as we see it and moved towards complete abstraction.
We evolve when we learn through discipline and develop dispassion and only then are we ready to discover the true nature of self.
Abstract, negate, strip down the layers, turn it upside down-as in there deep inside lies the truth.
Patañjali’s Yoga Sutras
Chapter 1, Samadhipadah
अभ्यासवैराग्याअभ्यां तन्निरोधः ॥१२॥
abhyāsa-vairāgya-ābhyāṁ tan-nirodhaḥ II12II
With sustained yoga practice and attaining dispassion one then develops nirodahah ( bringing a habitually surfing mind into a complete stoppage)
