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 jnani 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.
