(8.6) When we plan our travel, it requires careful planning and execution beforehand; we cannot make our plans after we pack our baggage. 

(8.7) Shri Krishna gives the ultimate teaching to all of mankind in this shloka. Since the thought at the time of death determines our fate after death, and the thought of death is an outcome of our lifelong thinking, Shri Krishna instructs us to remember Ishvara at all times and perform our duties.
