Krishna says, "I am the Vedic ritual; sacrifice; oblation offered to the ancestors. I am the medicinal herb; the 𝙢𝙖𝙣𝙩𝙧𝙖 (chant); 𝙖𝙟𝙮𝙖 (clarified butter); 𝘼𝙜𝙣𝙞 (fire) and the act of offering (9.16). Of this universe, I am the Father; I am also the Mother, the Sustainer, and the grandfather. I am the purifier, the goal of knowledge, the sacred syllable Om. I am the 𝙍̣𝙞𝙜 𝙑𝙚𝙙𝙖, 𝙎𝙖𝙢𝙖 𝙑𝙚𝙙𝙖, and 𝙩𝙝𝙚 𝙔𝙖𝙟𝙪𝙧 𝙑𝙚𝙙𝙖" (9.17).
"I am the ultimate goal, the upholder, Lord, Witness, Abode, Shelter, and Friend. I am Origin, 𝙋𝙧𝙖𝙡𝙖𝙮𝙖 (cosmic end), and the Foundation, Treasure house, and Eternal Seed (9.18). I radiate heat and give or withhold the rain. I am 𝙖𝙢𝙧𝙪𝙩𝙖𝙢 (immortality) as well as 𝙢𝙧𝙞𝙩𝙮𝙪 (death). I am the 𝙨𝙖𝙩 (real or being) as well as 𝙖𝙨𝙖𝙩 (unreal or illusion)" (9.19).
If the all inclusive existence had to describe itself for our understanding, it would sound like this. The context and words used are of the times when the Gita was given to Arjun.
Krishna earlier told Arjun to understand '𝙨𝙖𝙩' and '𝙖𝙨𝙖𝙩' (2.16) like the proverbial rope and illusionary snake which is the approach of 𝙎𝙖𝙣𝙠𝙝𝙮𝙖 𝙔𝙤𝙜𝙖. Now Krishna says that HE is both '𝙨𝙖𝙩' as well as '𝙖𝙨𝙖𝙩' which is 𝘽𝙝𝙖𝙠𝙩𝙞 𝙔𝙤𝙜𝙖. One path to 𝙋𝙖𝙧𝙖𝙢𝙖𝙩𝙢𝙖 is to attain the ability to separate '𝙨𝙖𝙩' and '𝙖𝙨𝙖𝙩' and another is to realise that they are both HIM.
These examples help us ascertain that we are on the firm path towards realising 𝙋𝙖𝙧𝙖𝙢𝙖𝙩𝙢𝙖 as long as we can remember HIM whenever we get a glimpse of any one of these examples. It is as simple as remembering 𝙋𝙖𝙧𝙖𝙢𝙖𝙩𝙢𝙖 when we see rain; remembering HIM when we see birth as well as death; when we see fire. Essentially, it is developing an attitude to see HIM in everything around us.
