तस्मात्सर्वेषु कालेषु मामनुस्मर युध्य च।
8.7 Therefore, think of Me at all times and fight. There is no doubt that by dedicating your mind and intellect to Me, you will attain Me alone.
8.7 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 Srutis 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 ones end is dependent on ones last thought, Sri Krsna proceeds to describe different modes of contemplation (Upasana) to be practised by the three groups of devotees for aciring 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.
