This the way Sri Aurobindo describes in Savitri (pp. 526-527) how our soul helps us to endure "mid the labour of the stars":
... since she knows the toil of mind and life
As a mother feels and shares her children’s lives,
She puts forth a small portion of herself,
A being no bigger than the thumb of man
Into a hidden region of the heart
To face the pang and to forget the bliss,
To share the suffering and endure earth’s wounds
And labour mid the labour of the stars.
This in us laughs and weeps, suffers the stroke,
Exults in victory, struggles for the crown;
Identified with the mind and body and life,
It takes on itself their anguish and defeat,
Bleeds with Fate’s whips and hangs upon the cross,
Yet is the unwounded and immortal self
Supporting the actor in the human scene.
Through this she sends us her glory and her powers,
Pushes to wisdom’s heights, through misery’s gulfs;
She gives us strength to do our daily task
And sympathy that partakes of others’ grief
And the little strength we have to help our race,
We who must fill the role of the universe
Acting itself out in a slight human shape
And on our shoulders carry the struggling world.
This is in us the godhead small and marred;
In this human portion of divinity
She seats the greatness of the Soul in Time
To uplift from light to light, from power to power,
Till on a heavenly peak it stands, a king.
