saptārṇavaḥ sapta kulācalāśca saptarṣayo

The Navagraha refers to the nine celestial bodies in Hindu astrology, which include the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, and the two lunar nodes, Lord Rahu and Lord Ketu. These celestial bodies are considered to have a significant influence on human lives and are often worshipped to mitigate their adverse effects and to seek their blessings for prosperity and well-being. This shloka is a morning invocation seeking the blessings of the Navagraha. It mentions the seven oceans, seven mountain ranges, seven sages, seven islands, and seven forests, along with the seven worlds beginning with Bhur (Earth).
