Element of Mahat (મહત્) is also the highest part of the ego. The most Satwik (pure and holy) and subtlest of the subtle part of the ego is Element of Mahat. When Mahat comes in forefront, there is creation. Creation is not possible without ego. Creation in this world and universe is because of ego.
Consciousness is already present. Element of Mahat came out of it. Ego came out element of Mahat. Purush (soul) and prakruti came out from ego.
Ego is destroyed last in the path of Bhakti and knowledge. It is hardest to destroy the ego since everything is present because of it. The creation that happens by us is because of ego. Creation done by us in the field of Karma or in any other field, is because of ego. It is best if we do not exercise our ownership of the ego. This means, it is best if we do not feel or understand that 'we did that work'. It is not that we cannot create with ego just because there is no understanding of ego.
Everything happens because of the strength of Bhagwan. Ego is a kind of strength of Bhagwan but since it is covered with Prakruti, it keeps us constantly connected with Prakruti.
When ego is completely destroyed, there is expression of the Chetan (consciousness) with form. It is not my understanding that expression with form means there is some kind of visualization of the form. My understanding is that there is expression of characteristics of Chetan in life. First there is expression and visualization with form. It is not necessary that one will have visualization of formless expression of Chetan just because of the experience of Chetan with form. Both are completely independent of each other. It is also not that one is of higher category than the other. Most of the time, there is experience of Chetan with form. Occasionally someone experiences Chetan without form.
