What is the essence of the words Guru, Shree and Prabhu?

[Shri Jayesh Pandey: Submissions at Your feet Swami ji!]

Swami replied:- Guru means preacher of knowledge, Knowledge means Veda and God Brahma is the author of the Veda. Shrii means Goddess Lakshmi and God Vishnu is the husband of Goddess Lakshmi. Prabhu means Lord, which is the meaning of the word Iishvara meaning God Shiva. These three words in this sequence mean God Brahma, God Vishnu and God Shiva resulting in the unified root form, God Datta.
