妙法蓮華經文句 2.55

2.55

觀釋者，中觀廣博名大；無緣慈名愛；中理虛通名道。大即自行；愛即化他，如以愛故受生，慈故涉有；道即通自行、化他也。

The contemplative explanation: the middle contemplation being vast and broad is called 'great'; causeless compassion is called 'love'; the principle of the Middle being empty and unimpeded is called 'the Path'. 'Great' is one's own practice; 'love' is converting others, as taking birth on account of love and entering existence on account of compassion; 'the Path' connects both one's own practice and converting others.
