The Bhagavad Gita was a live conversation where Krishna was observing Arjun in totality. Krishna must have observed an expression of doubt or disbelief on Arjun's face when Krishna mentioned 'to remember HIM all the times and fight' (8.7) as Arjun was resisting the 'work at hand' (Kurukshetra battle). This tendency of resistance to the work at hand is still prevalent.
Krishna immediately describes HIMself as the Omnipresent, Eternal, the Great Ruler, Subtler than the finest atom, Supporter of all, of inconceivable form, Shines like the sun, beyond darkness (8.9). When existence has to describe itself even words fall short.
Krishna gives two paths to remember HIM. One is the path of awareness and says, "He attains the Supreme Effulgent Lord whose mind, stabilized by yoga, is immovably fixed on the thought of Him" (8.8).
The mind is evolved to divide the sensations brought by senses and this division is the birthplace of polarities of pleasure and pain (2.14). Though useful for physical survival or animalistic living, this ability needs to be kept under control. Krishna suggests the path of awareness i.e. yoga of equanimity to attain this state.
The second path is a technique based on devotion. Krishna says, "One who, at the time of death, fixes his ๐ฅ๐ง๐๐ฃ๐ (life breath) between the eyebrows and in full ๐๐๐๐ ๐ฉ๐ฎ๐ (devotion) engages himself in remembering the Supreme Lord, will certainly attain HIM" (8.10). Though this path appears easier than the first path of controlling the ever wandering mind, devotion or ๐๐๐๐ ๐ฉ๐ is the prerequisite for it.
๐ฝ๐๐๐ ๐ฉ๐ and ๐๐๐ง๐๐๐๐๐ are the common threads in the Gita. ๐ฝ๐๐๐ ๐ฉ๐ is unconditional love flowing from our hearts irrespective of outer conditions like the fragrance of a flower. ๐๐๐ง๐๐๐๐๐ is accepting anything coming our way as the blessings of the ๐ฅ๐๐ง๐๐ข๐๐ฉ๐ข๐ without any resistance.
