心是什么？长什么样？当我们没有审视内心时，念头此起彼伏，力量巨大，有时一个念头就是全世界，一种情绪就能让人跳楼。一旦开启内心的观照力，去审视念头到底是什么，就会发现“觅心了不可得”。因为所有念头的本质都是空性，是无形无相的。
What is the mind? What does it look like? When we do not examine our inner thoughts, they arise and pass away with great power. Sometimes, a single thought can feel like the entire world, and an emotion can drive someone to jump from a building. Once we cultivate the ability to observe our inner mind and scrutinize what these thoughts truly are, we discover that 'the mind cannot be found when sought.' This is because the essence of all thoughts is emptiness—formless and without inherent characteristics.
