Your mistaking it. The 14 realms/worlds as stated are the 14 plains of existence in the material world. These are divided into 3 - the higher (spiritual), the intermediate (self-explanatory) and the lower totally material.. so there are 14 of which each are part of the 3 divisions. The universe is spherical in shape and contain all of these. Aboding Above all and inside all is the creator is WAHEGURU. 🙏🏽
