Premanand Maharaj Ji

Do I have to give up my family to free myself from attachment?

Love family, seeing Bhagwan in them

No, you need not give up your son. Love him and your family, seeing Bhagwan present in each of them, and then no obstacle will remain for you.

If you love your son as a body, attachment will arise. If attachment arises, bhakti to Bhagwan will not happen.
