kleso ’dhikataras tesam avyaktasakta-cetasam avyakta hi gatir duhkham dehavadbhir avapyate
ye tu sarvani karmani mayi sannyasya mat-parah ananyenaiva yogena mam dhyayanta upasate
TRANSLATION
Those devotees who have their fixed mind on the Invisible (Unmanifested) have more difficulty because it is tough to retain the Unmanifest. But those who worship Me by surrendering all their actions unto Me, devoted to Me, and meditating upon Me, with single minded devotion.
