WHETHER BHAGAVAD GITA SHOULD NOT BE APPLIED TO NON-SPIRITUAL PURSUITS?

Bhagavad GItA has the main objective of Bhakti Yoga . But there are other valued aspects related to Karma and JnAna as well. Karma Yoga can be applied to both materialistic pursuits and religious/spiritual endeavors. The principles are the same. While one is about society another is  regarding divinity. Instead of not doing any thing (Karma SanyAsa) Karma Yoga is far superior. The philosophical inputs of Gita appeals to the mind, body and intellect representing Bhakti, Karma and JnAna Yogas. We can emulate best practices of great men as well both at the materialistic and religious / spiritual levels:

Yadyat Acarati Sreshthah tadtadevetaro janah !
sa yat pramANam kurute lokas tadanuvartate !!
