Meaning -
Brhaspati, lord of unbounded rain and thunder, come and bless me as the epitome of divine powers, whether you are Mitra or Varuna or Pusha or commander of the Marut winds with Adityas and Vasus. Let the cloud rain for the man of peace and lover of knowledge.$(This mantra is a prayer for physical as well as for spiritual rain of water and peace for the lover of knowledge and peace. Brhaspati, Mitra, Varuna and other devas are physical powers of rain, and this process of vapourisation, electric catalysis of gases and condensation has been explained in his essays on the composition of water and atmosphere by late Pandit Gurudatta Viyarthi in his book Wisdom of the Rshis, republished by Dr. Ravi Prakash Arya, Email : vedicscience@hotmail.com).
