5.20 न not? प्रहृष्येत् should rejoice? प्रियम् the pleasant? प्राप्य having obtained? न not? उद्विजेत् should be troubled? प्राप्य having obtained? च and? अप्रियम् the unpleasant? स्थिरबुद्धिः one with steady intellect? असम्मूढः undeluded? ब्रह्मवित् knower of Brahman? ब्रह्मणि in Brahman? स्थितः established.Commentary This is the state of a Jivanmukta or a liberated sage or a Brahmana who identifies
himself with the Self or Atman. He always has a balanced mind. He is never deluded. He has abandoned all actions as he rests in Brahman. He who has an unbalanced mind? who identifies himself with the body and mind feels pleasure and pain? exhilaration of spirits when he gets a pleasant object and grief when he obtains an unpleasant object.
