Taranjeet Singh ji thanks for your post.

One thing if I may observe is the following. In common usage when someone mentions someone's/something/etc. name, we immediately get a picture of the aspects we know of,

• Where lives/belongs
• Where works/what delivers
• What does
• Who are relations
• What is good about ....
• What is bad about ....
• What I don't know
• ............... and so on

So for me at least, the name is just a marker of all the information, understanding, knowledge we have about the referenced object, person, concept, persona, etc.

Can we have a name reference when we don't fully understand? Of course we can. Does the name change when we know more? No it is the same. So Waheguru, creator, etc., they don't change, our understanding and knowledge increase. Is there a magic moment when we reach a level of critical and as much as possible knowing state of Waheguru? There probably is and it for sure requires Guru's grace or Gurparsad as referenced in Sri Guru Granth Sahib Ji.

Just some thoughts,

Sat Sri Akal.
