Every piece of knowledge must be digested to liberate more fire/spirit from itself.
It is similar to real fire from firewood.
If you put dry wood, it further enhances the fire.
Whereas if you put wet wood, it diminishes it.
Similarly, if knowledge quells the fire, then that knowledge is not serving the fire.
There is no good knowledge or bad knowledge.
However, whether your fire can handle the knowledge or not is the real question,
i.e. whether you have the necessary supports, enzymes, tools etc. to digest it or not,
And that is what needs your discretion.
Knowledge must serve and enhance your spirit,
Like dry firewood enhances and fuels the fire.
If the knowledge being consumed does the reverse,
Then that knowledge is not serving your spirit,
And it would then diminish your life force.
Every answer you get for a question,
When digested fully, will spark 10 other subtler questions.
The purpose of an answer is to act like an enzyme to break the question up into subtler and subtler questions.
In a way, this principle also holds true for physical food.
If you can digest what you eat, the the food serves you and increases your energy.
If the food takes more energy to digest than it provides,
It leaves you with lesser energy than when you started off.
