In plain words
There is nothing whatsoever higher than Me, Dhananjaya. All this is strung on Me like clusters of jewels on a thread.
Word for word
Than Me there is not anything other higher, O Dhanañjaya; on Me all this is strung, like clusters of gems on a thread.
मत्तः परतरं नान्यत् किञ्चिदस्ति धनञ्जयमयि सर्वमिदं प्रोतं सूत्रे मणिगणा इव

▸Bhagavadgītābhāṣyam
यतः तस्मात् —
मत्तः परमेश्वरात् परतरम् अन्यत् कारणान्तरं किञ्चित् नास्ति न विद्यते, अहमेव जगत्कारणमित्यर्थः, हे धनञ्जय । यस्मादेवं तस्मात् मयि परमेश्वरे सर्वाणि भूतानि सर्वमिदं जगत् प्रोतं अनुस्यूतम् अनुगतम् अनुविद्धं ग्रथितमित्यर्थ, दीर्घतन्तुषु पटवत् , सूत्रे च मणिगणा इव ॥ ७ ॥
In plain words
Because that is how things stand, therefore —
There is nothing higher than me, the Supreme Lord. No other cause, no second origin, nothing of the kind at all — look for it and it is not there. I alone am the cause of the world: that is what the verse is saying, Dhanañjaya. And because that is how it stands, all beings, this whole world, are woven into me, the Supreme Lord — stitched along me, running through me, pierced through and strung on me. Cloth on its long threads. Gems on a single string.
Close to the Sanskrit
Since [it is so], therefore —
Than me, the Supreme Lord, there is nothing higher whatever, no other cause — it is not, it is not found. The meaning is: I alone am the cause of the world, O Dhanañjaya. Because it is so, therefore in me, the Supreme Lord, all beings — this whole world — are woven: stitched along, run through, pierced through, strung together; that is the meaning — as cloth is on its long threads, and as clusters of gems are on a string.
