…the stage of sannyasa, just like we have adopted, this is a practical example how much one has been able to become free from bodily affection. This is a chance. This is a chance given. Just like at home I have my wife, I have my children, I have my grandchildren, everyone, I have my daughters and everyone, but somehow or other, I have thought that "What is this relation?" Therefore I have been able to live aloof from these bodily relatives. And actually, in this old age, one should desire to live within the family with wife, with children and there are so many comforts. But no. The development of one's consciousness is that he should voluntarily, voluntarily try to become free from this affection. Why? This affection is not bad, but this affection will lead me again to have another body. My whole process is that how to get out of this bodily relation, janma-mrtyu-jara vyadhi [Bg. 13.9]. The whole human activities should be concentrated to get rid of this bodily, material bodily connection. Then I
shall be happy really. Real happiness, real freedom.
