What is the difference between Nirguna Brahma and Saguna Brahma?

[Shri Jayesh Pandey asked: What is the difference between Nirguna Brahma and Saguna Brahma? Does the Nirguna Brahma ever get affected by the creation?  Are the Nada Brahma and Jyoti Brahma devoid of emotions? These set of questions may indicate to you the state of my mind currently Swami ji. At Your feet. May Hanuman ji bless us All! Dandvat Namaskaram to Swami ji and to His devotees!]

Swami replied: Nirguna Brahma is the unimaginable God, who is beyond space and time. He is beyond your imagination and you can’t think about Him even if you try for millions of births. Saguna Brahma is the mediated unimaginable God, who is very easily accessible for meditation. There is no difference between Nirguna and Saguna Brahmans. A hundred rupee note given to you directly is Nirguna Brahma. The same note put in a cover is Saguna Brahma. If you are praying to Saguna Brahma, it means that you are praying to Nirguna Brahma only. The medium of the unimaginable God helps you to meditate upon Him.

Nāda Brahma is nothing but the voice of the mediated God. Jyoti Brahma is nothing but the glow present on the face of the mediated God.
