They say what you believe eventually comes true and I don't believe
'advaitins' are any different in that, though they may accept that all
belief as an individual concept, has to eventually disappear.
('beyond' that there would be no such name)
It is thus said that we never doubt that anoher breath will come, one
step follow another, or that sleep will not be followed by waking,
only because we believe it 100%, as with the rest of our apparent
existence. So in the same way, usng the power of belief to conceive of
a personalised god, an 'other' greater self that personifies the
'answer' to life's apparent deficiencies, can lead to its fulfilment,
as countless saints and sages, not least Sri Ramakrishna have
attested. The latter's story is particularly relevant in that he
realised the continuous divine presence of his 'mother', godess Kali,
first, but later was obliged to 'cut her image in two' before he could
merge in the supreme formless Brahman. Interestingly it was Kali
herself (who else) who, as she told him, brought the advaitin Totapuri
to teach him just that.
The communal imagination/belief of Hindus in the seemingly eternal
family of gods and goddesses and their countless stories - all
directed to encouraging self-knowledge and indeed the final negation
yet inclusion of all such concepts, is IMHO one of the crowning
glories of human culture. But that's a 'personal' view and derived
from some years immersed in that environment; nevertheless,
imagination/belief is as much anyone's right as it is their state of
being.
