" We men are easily prone to sins of thought. Therefore, He who has formed each heart individually, knowing that the impulse received from the intention constitutes the major element in sin, has ordained that purity in the ruling part of our soul be our primary concern. "
- Saint Basil

The quote emphasizes that human beings are particularly susceptible to immoral thoughts, which can lead to sinful actions. It suggests that God, who intimately understands each person's heart and intentions, has decreed that maintaining purity of thought should be our top priority. This purity pertains to the mind or soul, as it is believed that the intention behind an action plays a crucial role in determining its moral worth.

Delving deeper into this quote, we can see that Saint Basil is advocating for a proactive approach to morality and spirituality. He believes that thoughts are the seeds of actions; therefore, keeping one's intentions pure and wholesome is essential to prevent sinful deeds from occurring. By focusing on purity of thought, individuals can cultivate virtuous behavior and strengthen their moral character. Additionally, this perspective underscores the importance of self-awareness and introspection in personal spiritual growth and ethical development.
