Below we have compiled many verses, mostly from SB and BG
For Understanding why “good and bad” things happen to us,and more specifically how each of us individually reacts to such events as devotees or Vaisnavas. The ultimate goal of all action, according to our philosophy is to only act for the satisfaction of God, or Krsna, and in that way no personal karma is generated. OK here we go….
SB 1.17.18 O greatest among human beings, it is very difficult to ascertain the particular miscreant who has caused our sufferings, because we are bewildered by all the different opinions of theoretical philosophers.
PURPORT
There are many theoretical philosophers in the world who put forward their own theories of cause and effect especially about the cause of suffering and its effect on different living beings. Generally there are six great philosophers: Kaṇāda, the author of Vaiśeṣika philosophy; Gautama, the author of logic; Patañjali, the author of mystic yoga; Kapila, the author of Sāṅkhya philosophy; Jaimini, the author of Karma-mīmāṁsā; and Vyāsadeva, the author of Vedānta–darśana.
Although the bull, or the personality of religion, and the cow, the personality of the earth, knew perfectly well that the personality of Kali was the direct cause of their sufferings, still, as devotees of the Lord, they knew well also that without the sanction of the Lord no one could inflict trouble upon them. According to the Padma Purāṇa, our present trouble is due to the fructifying of seedling sins, but even those seedling sins also gradually fade away by execution of pure devotional service. Thus even if the devotees see the mischief-mongers, they do not accuse them for the sufferings inflicted. They take it for granted that the mischief-monger is made to act by some indirect cause, and therefore they tolerate the sufferings, thinking them to be God-given in small doses, for otherwise the sufferings should have been greater.
