Seth: ‘The you that you are can make any changes you want to in your experience: You can change probabilities for your own purposes, but you cannot change the courses of other probable selves that have gone their own ways. All probable selves are connected. They each influence one another. There is a natural interaction, but no coercion. Each probable self has its own free will and uniqueness. You can change your own experience in the probability you know – which itself rides upon infinite other probabilities. You can bring into your own experience any number of probable events, but you cannot deny the probable experience of another portion of your reality. That is, you cannot annihilate it.
As you are looking at one photograph in your personal history, that represents your emergence in this particular reality or the reality that was accepted as official at the time it was taken – so you are looking at a picture of a representative of your species, caught in a particular moment of probability. That species has as many off-shoots and developments as you have privately. As there are probable selves in private terms, there are probable selves in terms of the species. As you have your recognized, official past, so in your system of actuality you have more or less accepted an official mass history. Under examination, however, that history of the species shows many gaps and discrepancies, and it leaves many questions to be answered.’ (session No 695)
'Everything about parallel realities':

While Bashar is rather employing the term 'parallel self', or 'parallel version of you', in his cosmology Seth is mainly focusing on 'probabilities' and 'probable selves', which are basically in line with Bashar. As Seths' concepts are more comprehensive, they help elucidate the complex nature of multidimensional reality. In the case of Bashar it is never entirely clear whether he is talking about:
a) former or future lifetimes of the 'greater you that you are',
b) overlapping lifetimes lived concurrently with yours,
c) the lives lived (by other portions of yourself) in parallel dimensions, or merely
d) the frames (reality production frames) you have left a moment earlier while shifting through an infinite number of them, thus creating the illusion of time and movement.
In the case of Seth, probabilities follow the qualifiers of 'likeliness' and 'significance', emanating from the 'inside' of any given activity or situation (similar to a fractal when visualized). For Bashar everything which can be conceived of must be by definition happening somewhere, somehow - otherwise it would not be part of 'All-that-is', i.e.: otherwise 'All-that-is' would not be ALL it could be.
