mayy eva mana ādhatsva mayi buddhiṁ niveśhaya
nivasiṣhyasi mayy eva ata ūrdhvaṁ na sanśhayaḥ|| 8||

My Understanding : Krishna is the ultimate guide who shapes your actions; decisions originate from Him, while their execution is carried out by the human. The individual is merely an instrument in His divine plan. Surrender yourself completely to Krishna, aligning your mind, heart, and soul with Him, for He is the true doer of all.
