This is one of the most operationally significant verses in the entire Gita. Krishna gives the ultimate, paradoxical command. Therefore (tasmāt), at all times and in all circumstances without exception (sarveṣu kāleṣu), constantly remember and think of Me (mām anusmara), and simultaneously, FIGHT (yudhya ca). By completely dedicating, offering, and surrendering your mind and your intellect to Me (mayy arpita-mano-buddhir), you will absolutely come to Me and attain Me (mām evaiṣyasi), of this there is no doubt (asaṃśayam).
