From the Bible:

Jesus Christ demonstrated this perfect surrender to God’s will in the Garden of Gethsemane, the night before he was captured and imprisoned, preparatory to his crucifixion. He went apart from the others to pray, and asked them to pray also. But when he returned to them he found them asleep.

Out of his love for them he excused them, saying, “The spirit indeed is willing, but the flesh is weak.” He then urged them again, saying, “Watch and pray.”

From the Bhagavad Gita in the thirteenth Chapter:

Humbleness, truthfulness, and harmlessness,
Patience and honor, reverence for the wise,
Purity, constancy, control of self,
Contempt for sense-delights, self-sacrifice,
Perception of the certainty of ill
In birth, old age, and frail mortality,
Disease, the ego’s suffering, and sin;
Detachment, lightly holding thoughts of home,
Children, and wife – those ties which bind most men;
An ever-tranquil heart, heedless of good
Or adverse fortune, with the will upraised
To worship Me alone, unceasingly;
Loving deep solitude, and shunning noise
Of foolish crowds; calm focus on the Self
Perceived within and in Infinity:
These qualities reveal true Wisdom, Prince.
All that is otherwise is ignorance!
