ये तु सर्वाणि कर्माणि मयि संन्यस्य मत्पराः। अनन्येनैव योगेन मां ध्यायन्त उपासते ॥

ye tu sarvāṇi karmāṇi mayi sannyasya mat-paraḥ ananyenaiva yogena māṁ dhyāyanta upāsate

In plain words: Krishna speaks of those who offer all their actions to him, focus on him, and worship him in meditation with their whole heart. The next verse finishes the thought.
