妙法蓮華經玄贊 2.26

2.26

三攝取眾生方便，以不捨眾生故。此攝一句，以慈修身，由以大慈悲熏習身心，故能不捨一切眾生，常能救度。

Third, the skillful means of integrating sentient beings, because they do not abandon sentient beings. This subsumes one clause: 'cultivating the body with loving-kindness.' Because through great loving-kindness and compassion they perfume body and mind, they can refrain from abandoning all sentient beings and constantly deliver them.
