התבוננות (Class Three). The point of the התבוננותו is וידעת היום so that it should bring to the והשבות אל לבבך. The Mitteler Rebbe writes that התבוננות must be in details so it should truly arouse the heart. Ironically the mind and heart contradict each other (unless one is on the level of פנימיות המוח והלב which is sometimes called מוחין ומדות דגדלות) and the work is to suppress the heart (delay it) so the mind can delve more deeply so the ultimate emotion (התפעלות) will be deeper. The challenge of bringing the mind to the heart and emotion.
