Meaning
Krishna is the origin of all. Everything emanates from Him. The wise who fully understand this engage in His worship with great devotion and ecstasy.
मैं ही सबका प्रभव स्थान हूँ; मुझसे ही सब विकास को प्राप्त होता है, इस प्रकार जानकर बुधजन भक्ति भाव से युक्त होकर मुझे ही भजते हैं।
This is verse 8 of 42 in Chapter 10 (Vibhooti Yoga) of the Bhagavad Gita.
