Bookish Knowledge, is simply conditional/contextual statements, not truths,

 

 Bookish Knowledge,is simply conditional/contextual statements, not truths, ---

bound by local parameters/times, have momentary/local value, meager.

we must avoid them scrupulously, lest they limit our creativity by trapping us/binding us, leading us to fall for the temptation to become inebriated with the exuberance of our own verbosity , missing the real track of expressing some thing worthwhile.

they pollute our mind like fast food
also lead us to ego states to exhibit 

at the end of sivananda lahari, sankara wrote a nice things about writing,
also indicating wisdom to do priority things, ''nahi nahi rakshathi du krun karani'' 

Also these verbose have attraction, without value, reader is tempted to think that he is enjoying with them, while really they cause damage.
it's necessary to carefully consider all, and go for the best without bias, --after all every thing has relative value--one is more valuable and other is less valuable--this a hard fact of things

if a thing is mine, it does not automatically become the best
whether it is ours or others', value decides worth, and we must differentiate pearls from pebbles and rubbles
this is true in any language, some never knew full truth, they express half truth as a glorified thing, good at questioning and display of vocabulary and appearing to possess knowledge , failing to answer truly.

once full truth is known only, we come to know where to place them, in the importance, truth being our concern, experience of it providing authenticity to our expression, clarity like daylight

 various aspects have influencing factors of history, geography, compulsions compromises, contingencies, and expediency in every writer 
question is whether expression illumines our path in a little way at least or not, or becomes a obstacle

Writing, dance, singing, painting .....every movement, every thought every impulse are ways of expressions all trying to bring out the truth cognized ...as precisely as fully as is possible.

expression becomes artistic, in proportion to the depth mind reaching inside.
in the ultimate level mind goes beyond and becomes able to cognize truths , and expresses as richa , the most valuable of the expressions ..form can be any, including writing
