Krishna mentioned that four types of devotees worship him; to remove their difficulties (𝙖𝙧𝙩𝙖𝙝), to attain success (𝙖𝙧𝙩𝙝𝙖𝙧𝙩𝙝𝙞), to obtain knowledge (𝙟𝙞𝙜𝙣𝙖𝙨𝙝𝙪) and a 𝙟𝙣𝙖𝙣𝙞 (wise) (7.16). He elaborates about the 𝙟𝙣𝙖𝙣𝙞 and says that the 𝙟𝙣𝙖𝙣𝙞 who is 𝙣𝙞𝙩𝙮𝙖-𝙮𝙪𝙠𝙩𝙖 (ever steadfast) with single pointed devotion is the best among all devotees. I am extremely dear to 𝙟𝙣𝙖𝙣𝙞 and he is dear to me (7.17). At the end of the many 𝙟𝙖𝙣𝙢𝙖 (births), the man of wisdom reaches Me (7.19).
Many '𝙟𝙖𝙣𝙢𝙖' is usually interpreted that we should go through many births to become the 𝙟𝙖𝙣𝙢𝙖 though there appears to be no reason for this. Another interpretation would bring clarity by taking '𝙟𝙖𝙣𝙢𝙖' as a generic word rather than specific to the creation of our physical body. It can be '𝙟𝙖𝙣𝙢𝙖' of a situation or circumstance around us which is a continuous process. These can be favourable or painful but all of them have the potential to teach us and it is about how quickly we learn without getting attached to or developing an aversion to them.
Krishna earlier emphasised about learning through prostration, questioning and service (4.34). These three tools can be used for every situation we face, for people in our lives and for circumstances we are in. When approached with 𝙨𝙝𝙧𝙖𝙙𝙙𝙝𝙖 (trust) each of them can become a 𝙜𝙪𝙧𝙪 (teacher). It is about making today better than yesterday; tomorrow better than today in terms of gaining awareness and shedding of 𝙖𝙝𝙖𝙣𝙠𝙖𝙖𝙧 by dropping comparison with others and by competing with self.
This process can take us to a point of eternal state or 𝙢𝙤𝙠𝙨𝙝𝙖 (ultimate freedom) where nothing is left to know and these situations just become 𝙙𝙧𝙖𝙢𝙖𝙨 of joy which is the state of a 𝙟𝙣𝙖𝙣𝙞. The onus is on us to attain this.
