In South India there is a class of professional dancers. They take a big jar on the head and dance without hand support. The head is shaved but they are well practiced in their art of dance that they the balance the pot. There are also many professional vendors in India selling fruits keeping basket on the head and carrying a child in other hand. They even move around streets canvassing, “We have got this fruit etc.” Still they manage to balance the basket on their head. These are crude examples to learn that everything can be done by Art of practice.
One may be very responsible in their work. But still their mind can be absorbed in the thoughts of God or Kṛṣṇa. sa vai manaḥ kṛṣṇa-padāravindayor. There is an example given by Rūpa Gosvāmī of a woman in love with a Man. She’s always thinking of that lover although she’s busy with household affairs. This means that if you love someone or want them very seriously you can think of them twenty-four hours in spite of being engaged in your duties. It is possible.
So things are to be adjusted as it is prescribed by great authorities. In this world one cannot live without working but still one has to become always God or Kṛṣṇa conscious. This art can be practiced in spite of being engaged in so many so-called material things. Since a devotee has nothing to do with material things, even if he works for maintenance of the body that is not material. Just like the great devotee Bhaktivinoda Ṭhākura, in spite of being a magistrate he wrote so many books. He was working in a different transcendental platform. That is possible by practice.
