Scholars speculate about the author of this monumental scripture and such other academic matters. May God bless them with success.
The Yoga-Vasistha is the greatest help to the spiritual awakening, and the direct experience of the Truth. This is certain. If this is what you want, you are welcome to Yoga-Vasistha.
The text abounds in repetitions which are, however, not repetitious. If you do not like (or need) repetition, then read just this one verse:
This world-appearance is a confusion: even as the blueness of the sky is an optical illusion. I think it is better not to let the mind dwell on it, but to ignore it. (I.3.2)
This verse occurs several times in the scripture and it seems to be the very essence of the teaching.
If that is not quite clear to you now, read the scripture. The numerous ways in which this truth is revealed will help open your mind.
It is wise to read just one page a day. The teaching is revolutionary. The biased mind does not readily accept it. After the daily reading, meditate. Let the message soak through.
An oft-recurring expression in this scripture is 'kakataliya' - a crow alights on the cocoanut palm tree, and that very moment a ripe cocoanut falls. The two unrelated events thus seem to be related in time and space, though there is no causal relationship.
Such is life. Such is 'creation'. But the mind caught up in its own trap of logic questions 'why', invents a 'why', and a 'wherefore', to satisfy itself, conveniently ignoring the inconvenient questions that still haunt an intelligent mind.
Vasistha demands direct observation of the mind, its motion, its notions, its reasoning, the assumed cause and the projected result, and even the observed and the observation - and the realisation of their indivisible unity as the infinite consciousness.
That is the uniqueness of this scripture which hence declares itself to be supreme:
Except through this scripture, one cannot gain what is good, now or at any time. Therefore, for perfect realisation of the supreme truth, one should fervently in¬vestigate this scripture alone. (VI.2.103)
It is, however the teaching that is supreme, not a book or a sage. Hence, Vasistha is bold enough to say:
If, however, one thinks it is not authoritative because it is of human origin, one can resort to the study of any other scripture dealing with self-knowledge and final liberation. (VI.2.175)
Whichever be the scripture taught, by whomever, and whichever be the path you choose, stop not till the psychological conditioning ceases entirely. Hence, Vasistha exhorts the seeker:
One should study at least a small part of this scripture daily. The beauty in this scripture is that its student is not abandoned to his despair; if something is not clear in the first instance, a further study of the scripture makes it clear. (VI.2.175)
