wisdom

knowing yourself is the first step of wisdom

dont open your tongue when your brain is in use

dont  open your brain when your heart is in use

If you win yourself - Your ego , your emotions , your tongue , your behavior - You can be the king of kings 

Better Understanding leads to sound knowledge :

Sensations : our sense organs make contact with their objects and produce sensations - may be pleasant or unpleasant . We get attracted towards pleasant sensations .

Cognition : we attend to something / someone or some act / deed / event - watch it / observe it - understand it and come to know about it .

Learning / experience : we face some situation in reality or in imagination that demands control or solution and we try to do that and all the learning adds to our experience . this adds to our judgement ability & wisdom .

Memory : all that we know / learn / experience - get registered / stored in our mind at unconscious level but we can recall it at our conscious level

Keep your Fist closed - do not disclose your power
Keep your Heart closed - do not express your feelings
Keep your Mind closed - do not express your planning
Ignorant People fear to open a closed box - curious as well
