NAmaskaram
I think what is being said is true and ideal, but to bring such drastic changes depends on our level of devotion and requires high purity..So if one is so pure then they can change the whole system.
But for an ordinary pious person who is slowly cultivating devotion, he cannot and should not fight the system to change it will be hypocritical.. but what he can do is to exercise his free will and choose the right leader,right country, right organisation etc.. prayers and desire will lead to right choice, but it might involve some compromise in material sense.
Another alternative is one can do whatever duty is assigned to him in a detached way as a matter of duty and use the results of work in Lord’s service in Prasadam, book distribution, temple donation etc.. then his motivation of work becomes different from the leader. This option is valid provided the leader is not committing heavy deviations away from sastra.. for such scenarios.. previous option of exercising freewill through prayers and desire to make right choice is best.
Note: Bheesamacharya though he fought on wrong side, he did it as a matter of service to increase the glories of the Lord. He was an instruemnt by which Lord taught us few lessons 1) Even if a Storng person like Bhismacharya is in the adharma side he will loose 2) The lord protects the devoteee’s promise and does nto care about his promise.(Sri Krishna broke his promise not to fight but kept the promise of Bhismacharaya that only Krishna’s fighting can protect Arjuna)
So Bhisma dev acted according to Lord’s plan and still was on wrong side in the fight..
So it is possible to be in service in any side but for normal people like us we need to be on right side.
