“When the intellect grows strong, it makes ready to pursue the love which quenches all bodily passions and which prevents anything contrary to nature from gaining control over the heart. Then the intellect, struggling against what is contrary to nature, separates this from what is in accordance with nature.
- St Isaiah the Solitary
