Qualities of a Brahm-Gyani

Previously, The basic criterion of a Brahm-Gyani was:
“When a person completely casts off all the desires of the mind;
And is satisfied in the self by the Self, then he is said to be the 'Sthitpragna')  
                                             (Bhagvad Geeta 2-55)
                                        ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ 

Further qualities of a Brahm-Gyani 

First of all, the Brahm-Gyani - not only knows Brahm, but also sees Him all around and all the time.  
                     “Yo maam pashyati sarvatra – sarvam cha mayi pashyati”
“One who sees me (Brahm) everywhere – and also sees me within everyone.” 
                                                             (Bhagvad Geeta 6: 30)

                 “Man saacha, mukh saacha soye

                   Avar na paikhai aikas binu koye

                   Nanak ehu lachhan Brahm-Gyani hoye” 

                                                 (Sukhmani Sahib)

The True One resides in his mind, and on his lips
He does not see anyone other than the ‘One’ -
Nanak says this is the characteristics of the Brahm-Gyani.

So, the first and the foremost quality of a Brahmgyani is to see the Almighty Lord 
everywhere and within everyone and everything. 
He feels that:
“Sabai ghat Ram bolay, Rama bolay, Ram bina ko bolay ray”
                                                                                   (Gurbani)
Having set the basic characteristics of a Brahmgyani, Bhagavad Geeta 
and the Adi Granth (SGGS) continue to describe the additional qualities of Brahmgyani in details. 
Bhagvad Geeta says:
                         Dukheshu anudvigmanaa 
In pain whose mind is not shaken (does not feel pain)
                        Sukheshu vigataspraha - 
Who is not affected by pleasure.
                        Veetraag bhaya krodhah

                          Svasthah -

                         Sam-loshtaashm-kaanchanah

                                       ~  ~  ~
Exactly same, almost word to word description of the Brahmgyani is given by the 9th Guru in the Adi Granth (GGS)
                           Jo nar ḏukẖ mai ḏukẖ nahī maanai. 
That man, who in the midst of pain, does not feel pain, 
                          Sukẖ sanehu ar bẖai nahi jaa kai kancẖan maati maanai. 
who is not affected by pleasure, affection or fear, and who looks alike upon gold and dust
                          Nah nindya nah usṯaṯ jaa kai lobẖ moh abẖimaanaa. 
Who is not swayed by either slander or praise, nor affected by greed, attachment or pride; 
                         Harakẖ sog ṯe rahai niaarau naahi maan apmaana. 
who remains unaffected by joy and sorrow, honor and dishonor
                        Aasa manasaa sagal tyaagai, Jag tay rahai niraasaa
who renounces all hopes and desires and remains desireless in the world;
                       Kaam krodh jeh parsay naahin - 
                       Teh ghat Brahm nivaasaa 
Who is not touched by lustful desires and anger; 
within that heart, God resides.
