There you will find nothing like imposing the ism in gita . It is a scripture containing the guidelines of life . If we deeply go it inside and do not take professional or political move always we find that it is a manual of humanity . Not very earlier but Manusmriti is a scripture containing the biased views of the same time . Not going for higher vedic thoughts people may like Upanishads talking in the way of finding spiritual teachings. In such other cases phrases like , sarve bhavantu sukhinah , sarve santu niramayah etc also do not come in any ism quality and can be recited very often to guide the holy way of life . Exclusively if we talk of bhagwadgita it is termed as the gyan obtained by rajrishis only in earlier times . Of course gita talks of the dakshye , the skill to obtain the immortality , amrit ashnute . The sankhyayoga which is the exclusive matter has been discussed in gita is as told to arjuna by lord krsna . Going through mahabharat we find lord krsna performing every gita thought adopted to kill the aggressors . Take the example of bhishma , drona or jayadratha every step adopted is very skilful .So gita contains all gist of win ,be the real life or the spiritual . As in a real life for example if we do not always have TRUMP in our cards ,never mind there is always a skill to win .
