Now I am thinking that I am working for my maintenance or for my family maintenance or for my society's maintenance or for my country's maintenance. You can go on, widening. Even if you work for international maintenization, maintenance, still, it is not perfect. Even if you work for the whole planetary system, that is imperfect. But when you work for Kṛṣṇa, Kṛṣṇa consciousness, that is the most perfect work. So we have to work with Kṛṣṇa consciousness. That is the perfection.
Just like several times I have discussed this point, that a big tree, if you have to pour water, then you have to pour water on the root. The tree has millions and billions of leaves, and if you go on pouring water in each and every leaf, neither you'll be able to pour water to all the leaves, neither it is possible to maintain the tree by pouring water on the leaves. You have to pour water on the root. Similarly, our work, our endeavor, whatever we may do, good work or bad work, if it is not done on account of Kṛṣṇa, then that will remain always imperfect. Always imperfect.
Therefore it is advised, yoga . . . yoga-sannyasta-karmāṇam: "You just give up your work or place your working capacity, energy." We have got some energy. We'll work or we'll do anything with our energy. So spiritual self-realization means that energy should be transferred for Kṛṣṇa, or God. That's all. Energy. We have got some stock of energy. That energy should be transferred. You can transfer that energy in so many ways. In whatever way you can do it, it doesn't matter; you have to transfer your energy for Kṛṣṇa.
