The qualities we strive to attain are referenced in Lao Zi’s book Dao de Jing (Tao-de-Ching). He describes the qualities of the sages and the importance of their natures in attaining our true potential.
Cautiousness (豫兮) like crossing an ice covered river
Hesitance (犹兮)like one keeping boundaries with his neighbours
Dignified(俨兮) like always being a guest
Simplicity (敦兮) like uncarved wood.
Openness (旷兮) like a valley
Obscurity (混兮) like muddy water
Fluidity (涣兮)like ice about to melt
These qualities will eventually give us the tools to be able to cultivate our practice deeper. They re- train our minds and bodies to be able to be nourished and strengthen our spirituality. When this starts, the training begins to move away from the pure physical to becoming a cultivation practice. After some time the self begins to harmonise internally and externally.
