五、一心支。心與定法一，故名曰一心。行者初證禪時乃即著定，而心猶依覺、觀、喜、樂之法，故有細微之散。若受喜樂心，自然與定法一，故名一心支。

Fifth, the factor of one-pointedness of mind. The mind being unified with the dharma of concentration is called one-pointedness of mind. When the practitioner first verifies dhyāna, they immediately become attached to concentration; yet because the mind still relies on the dharmas of initial application, sustained application, joy, and bliss, there is subtle scattering. When the mind that experiences joy and bliss naturally becomes unified with the dharma of concentration, it is therefore named the factor of one-pointedness of mind.
