In plain words
Truly, ordinary people do not set foot on an unholy path; so these petty intellects who take to the path of abuse have to be called lower, indeed, than ordinary people.
You may say, “Swami! We are ordinary people; when the forms we worship are reviled, how are we to bear it?” — Here is a small example: when a registered letter comes for you, if you sign for it and take it, what is in it belongs to you, and that will trouble your mind; but if you do not take it, it is re-directed and goes back to the very people who sent it. Abuse too is just like that. If you take it up, saying, ‘He has abused me!’, all that abuse comes falling on you yourselves! If you let it go, saying, ‘It is not for me; what has it to do with me?’, it goes to those very people, whoever those demon-minded ones are, and it reaches them alone. Whatever pain they long to cause to whomever, whatever pain they plot to inflict, all of it comes back to those very people by way of re-sound, reaction, reflection: it falls on them and no one else and harms only them; it gives them pain.
Look in the Bhāgavatam: Jarāsandha, Kaṃsa, Śiśupāla — what an end every one of them met! Śiśupāla's contempt brought ruin on none but himself. God is beyond the guṇas; your good itself gives you protection; your evil itself gives you punishment.
