BRS 1.2.255

Śrīla Rūpa Gosvāmī, then, recommends that one should not be attached to material sense enjoyment, but should accept everything enjoyable which is in relationship to Kṛṣṇa. For example, eating is necessary, and one wants some palatable dishes to satisfy his sense of taste. So in that case, for the satisfaction of Kṛṣṇa rather than for the satisfaction of the tongue, some palatable dishes may be prepared and offered to Kṛṣṇa. Then it is renunciation. Let the palatable dishes be prepared, but unless they are offered to Kṛṣṇa one should not accept them for eating. This vow of rejecting anything which is not offered to Kṛṣṇa is actually renunciation. And by such renunciation one is able to satisfy the demands of the senses. The impersonalists, who try to avoid everything material, may undergo severe austerities, but they miss the opportunity of being engaged in the service of the Lord. Thus their renunciation is not sufficient for perfection. There are many instances where, following such artificial renunciation without any contact with devotional service, the impersonalist again fell down and became attracted to material contamination. There are many supposed renouncers even at the present moment who officially become sannyāsīs, or renouncers, and outwardly claim that spiritual existence is truth and material existence untruth. In this way, artificially they make a show of renunciation of the material world. However, because they cannot reach the point of devotional service, they fail to achieve the goal, and they again come back to material activities, such as philanthropic work and political agitation. There are many examples of so-called sannyāsīs who gave up the world as untruth but again came to the material world, because they were not seeking their real repose at the lotus feet of the Lord. One should not give up anything which can be utilized in the service of the Lord. That is a secret of devotional service. Anything that can be utilized in advancing Kṛṣṇa consciousness and devotional service should be accepted. For instance, we are using many machines for the advancement of our present Kṛṣṇa consciousness movement, machines like typewriters, dictating machines, tape recorders, microphones and airplanes. Sometimes people ask us, “Why are you utilizing material products if you condemn the advancement of material civilization?” But actually we do not condemn. We simply ask people to do whatever they are doing in Kṛṣṇa consciousness. This is the same principle on which, in Bhagavad-gītā, Kṛṣṇa advised Arjuna to utilize his fighting abilities in devotional service. Similarly, we are utilizing these machines for Kṛṣṇa’s service. With such sentiment for Kṛṣṇa, or Kṛṣṇa consciousness, we can accept everything. If the typewriter can be utilized for advancing our Kṛṣṇa consciousness movement, we must accept it. Similarly, the dictating machine or any other machine must be used. Our vision is that Kṛṣṇa is everything. Kṛṣṇa is the cause and effect, and nothing belongs to us. Kṛṣṇa’s things must be used in the service of Kṛṣṇa. That is our vision.
