Since:
I am an Orthodox Hindu Yogi, and I shall chime in:
a] The definition of God is He is both omnipresent & omnipotent.
b] The definition of God is He is expanding His own Personal Energy to creat & maintain the Cosmos ---yet without any loss of creative/omnipotent powers.
c] The definition of God is He is present in three ways:
---Brahman (The Void);
---Param-atma (The localised nucleus/Soul of all animate & Inanimate things);
---Bhagavan (The original First person who is unlimitedlt full in ALL-Opulences) {this would be a Persona Suprema ~Not an Inanimate object};
ergo,
Hell is "seperation from the Supreme personality of Godhead, Krishna".
The seperation allows for free-will to travel anywhere one "presumes" to go.
Since, the mystery of Life is: The search for & the return to the inter-personal reciprocal pastimes in the association of: the Supreme personality of Godhead, Krishna.
To substitute anything or anyone else for the above maxim is Hell. yes, there are degrees of hellaciousness. We are free to explore all the varied life-forms [each of the 8,400,000 species of life engage in the same 4-Acts: Eat/Sleep/Mate/Defend] ---yet, the Souls are seeking the Supreme Personality of Godhead who is unlimitedly full in all (personal) **Opulences. ---since time-immemorial, we souls-in-the-material-world are seeking out this Coolest: **Richest, strongest, most beautiful, most intelligent, most famous & the most renounced [these are the 6-Opulences that God the Original Transcendent Person alone possesses in unlimited quantity & is also the originating reservior of all such 'Personal' opulences].
Crawling, slithering, flying, swimming, buzzing creatures along with all races of Humans are extensions/plenary expansions of the Original Persona ---Mankind is the anthropomorphised creations of the Supreme Personality of Godhead, Krishna.
How do I know this about the first Father of All Creation?
Mother Veda said so ---she said it via her disciplic succession without deviating from the blatant Absolute Truth. --thus there is no room to speculate as to what is the absolute truth of such matters.
