This is the formula of spiritual realization, that we should not stop our working capacity, the prescribed duty in which we are engaged. That is not to be stopped. If we stop work, and spiritual realization, for spiritual realization, we leave this world and go to the jungle or Himalaya and sit down there for meditation for spiritual realization, oh, how many people will be ready to do this thing? No. This is not for mass people. Lord Śrī Kṛṣṇa is prescribing something practical, which can be adopted by every one and all, without any distinction.
This point we have already discussed in the last day's meeting, that whatever you may be, it doesn't matter. You can realize the highest perfection of life, provided you work under the regulation of yajña. Yajñārthāt karma. There is no harm working, but the work should be done for the Supreme Lord, Yajña. Yajña means Viṣṇu. Because according to laws of nature, any work you do, it has got some reaction, and we are bound up by those reaction.
The Vedas also says, karmaṇā baddhyate jantuḥ. Karmaṇā baddhyate jantuḥ, that "All living entities, they are bound up in this material encagement on account of their different kinds of karma, or work." But here is the point, that you shall not be bound up by the reaction of your karma if you act it on behalf of Yajña, or Viṣṇu, or the Supreme Lord. That is the secret.
