Sree Sree Guru Gaurangau Jayatah!
It is the advice of Sri Narada to Dhruva, "Don't blame others for your own sufferings. We get similar kind of sufferings as we inflict upon others. As long as we have this ignorance of blaming others for our sufferings, we shall not get the Grace of God." Dhruva, taking the advice of his guru Narada, relinquished his ignorance of blaming others and called God's Name from the core of his heart with one-pointed devotion. All hindrances of Dhruva were removed and those persons who were hostile to him became favourable automatically, without asking for this. God controls and gives the fruits of our actions, not man. We should rectify our karmas (acts) and not blame others for our afflictions and drawbacks. We reap the fruits of our own actions. .
God and His absolute counterpart gurudev (bona fide guru) are impartial. God is equal to all. As He is Absolute (purna), nobody can bribe Him and nobody can force Him to do anything which is unjust. But God may test a devotee by putting him in adverse circumstances to qualify him to get the service of His Lotus Feet. We shall become successful in the test. Sincere souls will never be deceived. So do not be disheartened.
