Śrīmad-Bhāgavatam · Text 10.48.18
Who is speaking and story frame
युवां प्रधानपुरुषौ जगद्धेतू जगन्मयौ ।
भवद्भयां न विना किञ्चित्परमस्ति न चापरम् ॥ १८ ॥
yuvāṁ pradhāna-puruṣau
jagad-dhetū jagan-mayau
bhavadbhyāṁ na vinā kiñcit
param asti na cāparam
You both are the original Supreme Person, the cause of the universe and its very substance. Not the slightest subtle cause or manifest product of creation exists apart from You.
