Eknathji tells : You fix upon the goal, evaluate your powers and potentialities thoroughly and the mission dawns upon you as it dawned upon Swamiji.
These days it is advised to do SWOT analysis - Strengths, Weaknesses, Opportunities, Threats - and find out the best course that is available to one.
Eknathji further says : Everything in this world is purposeful. Nothing is without a purpose; even an atom has its own purpose in this expansive, vast and endless universe.
Having known this, we have to again introspect and find out what is the purpose of my life. What work am I suppose to do in this Kingdom of God? Slowly it would take us to the thought that There is nothing accidental. Because we do not know the purpose of causation, we feel the futility of germs, mosquitoes, flies and insects; but the creator of the universe has a purpose set for them also.
Eknathji further illustrate this with a story : We know the parable of the mountain and the squirrel. The mountain first scoffed at the squirrel saying "What is the use of your insignificant existence?" The squirrel smiled and replied, "That I do not carry forest on my back like you, is a fact. That you cannot crack a nut like me, is also a fact." Thus everybody has a purpose to fulfill.
Once we understand this, we can reorient ourselves fully in such a way that every act also can become useful and would take us to the goal.
