This Painting is depicting that, at the time of death the human face is leaving its color(existence) and an unknown force is colliding and taking its soul from extreme right to the left horizon( which is the imaginary space for life after death).
The painting is nothing but that particular moment when human body gets completely destroyed and transformed into new body and soul. This journey is ultimate journey in everyone's life and its not necessary that, next level of existence is always represented by dark space. In the left side you may also notice some geometric pattern and other motifs and some motions, which is my imagination of decoding human body and mind.
All the characters and story line is based on my imagination. Viewers are free to think more and enjoy the expression of the journey.
