大乘起信論裂網疏 6.22

6.22

修諸善行者，通則六度四攝，別則四種三昧：所謂常行三昧，如般舟等；常坐三昧，如一行等；半行半坐三昧，如法華等；非行非坐三昧，如覺意等也。心不懈退者，總明三種精進也。當念過去等者，被甲精進也；為令未來等者，攝善精進也；大悲利益等者，利樂精進也。

"Cultivating all good practices": generally it is the six perfections and four means of embrace; specifically it is the four kinds of samādhi—namely, the constantly walking samādhi, such as the pratyutpanna, etc.; the constantly sitting samādhi, such as the one-practice, etc.; the half-walking and half-sitting samādhi, such as the Lotus, etc.; and the neither-walking-nor-sitting samādhi, such as the awakening-of-mind, etc. "Without negligence or retreating in mind" generally clarifies the three kinds of vigor. "One should be mindful that throughout the past..." is armor-donning vigor; "to cause the future..." is the vigor that embraces the good; "with great compassion benefit..." is the vigor that benefits and delights.
