Shantideva has said that if you get accustomed to something, there is nothing in this world that is difficult.

寂天菩萨曾说：“如果习惯了某事，这世界就没有什么困难的。”

This is very much spoken by the Shantideva. Shantideva has whole chapter about how ignorant beings are controlled and ruled by the emotion.

寂天菩萨对此说了很多。寂天菩萨有整个章节谈论无明众生是如何受到感情的掌控和支配。
