TRANSLATION
Therefore, remember Me at all times and fight; with your mind and intellect set upon Me, you shall surely come to Me.
PURPORT
Therefore, at all times, until your departure, remember Me, day after day. Engage yourself in actions appropriate to your station and stage in life, which would make you remember Me. These actions are prescribed by the Shrutis and Smrtis and comprise the periodical and occasional rites. Thus, by this means, with your mind and intellect set on Me, you will remember Me at the time of death and thus attain to Me in the manner desired by you. There is no doubt about this.
Thus, having laid down the common principle that the attainment of one’s end is dependent on one’s last thought, Shri Krishna proceeds to describe different modes of contemplation (Upasana) to be practised by the three groups of devotees for acquiring their objectives. Of these, he first speaks about the modes of contemplation to be adopted by the seekers of enjoyments and power and the type of the last thought consistent with their contemplation.
