Chapter 12: Sloka 5

12.5

kleśo ’dhikataras teṣām
avyaktāsakta-cetasām
avyaktā hi gatir duḥkhaṁ
dehavadbhir avāpyate

kleśaḥ—trouble; adhikataraḥ—more troublesome; teṣām—of them; avyakta—unmanifested; āsakta—being attached; cetasām—of those whose minds; avyaktā—unmanifested; hi—certainly; gatiḥ duḥkham—progress is troublesome; dehavadbhiḥ—of the embodiments; avāpyate—achieve.

For those whose minds are attached to the unmanifested, impersonal feature of the Supreme, advancement is very troublesome. To make progrese in that discipline is always difficult for those who are embodied.
