What is the meaning of Prajnanam Brahma?

[Smt. Lakshmi Lavanya asked: Pada namaskaram Swami, My name is K Lakshmi Lavanya, I had a dream recently, in the dream, I was college student, I was listening Your knowledge while going to class room, while entering class room You said " PRAJNANAM BRAHMA", I kept phone in pause and sat on the first bench. Phani Swami is in class as lecturer and he also said "Prajnanam Brahma, Ade Asalaina Tattvam". I couldn't understand the meaning of this, I request You to please tell me the meaning of the message given by both of You, so that I can implement it in my daily life. Thank You Swami, pada namaskaram Swami.]

Swami Replied:- Jnaanam means knowledge in general and it may be mathematics or physics or medicine or engineering or economics or literature. Prajnaanam means the best knowledge. ‘Pra’ means the best. Prajnaanam means spiritual knowledge or knowledge of God. Prajnaanam is like the lion, which is the king of animals in the forest. The animals will cry as long as the lion does not roar. This is told in a Sanskrit verse “Na garjati mahātejāḥ…”. All other branches of knowledge are useful in this world for getting a livelihood. But, spiritual knowledge shows the way to live happily here as well as in the upper worlds after death. This earth as well as the upper worlds are under the rule and control of God only. He is the Lord of both Pravrutti (worldly life) as well as Nivrutti (spiritual life).
