Jai Sri Ganesha,
Know the truth of nature that water goes down by nature and fire goes up, water follows the truth of gravity but fire moves against it,
Nature of mind relates more to water, the habitual tendency of the mind is direct outward then down in the majority of cases with few exceptions,
Evolution of self is but nature but under the influence of mind it may turn to involution,
Evolution is mostly based on the truth of consciousness, expansion of consciousness is available when the man goes introverted,
May Lord Bless all,
Thanks, please
