"Try to understand. Our this Kṛṣṇa consciousness movement is a protest to the modern way of civilization. The leaders of the modern society, they want that people should be engaged in working like dogs and hogs and asses. They should not understand what is the value of life, what is the object of life. Let them always remain intoxicated, and sense gratification, and produce more product for sense enjoyment. This is modern civilization. All these factories... I understand that in this country the farmers are taxed so heavily that they are forced to work in the factory. This is a policy of the government leaders to engage people. If anyone wants to live peacefully, save time for developing Kṛṣṇa consciousness, then the leaders of the society or the government will not allow him to do so. This is the position.
So you are all fortunate, or you are so kind that you have joined this movement despite all these obstacles in this country. Not in this, all over the world. So don't be disappointed. Go on preaching this philosophy of Kṛṣṇa consciousness. There are many innocent people; they do not know what to do. There are four... For a preacher, there must be vigilance. A preacher will see four things: God, a devotee of God, innocent person, and envious, jealous persons. So a preacher should deal with these four items differently. So far God is concerned, we shall try to increase our love for God. This is one business. How? That is the arcanā-vidhi, to always be cautious, to offer foodstuff, early to rise, offer maṅgala-ārātrika, keep the temple very cleansed, yourself also. Without being cleansed, without being brāhmaṇa, śaucam-śamo damaḥ śaucam... We should always remember. When you come to the temple, don't think that 'Here is a picture of Śrī Caitanya Mahāprabhu or Rādhā-Kṛṣṇa.' They are not picture. You should know that personally they are present. You'll realize the personal presence by the quality of your devotional service. If your devotional service quality is not first class, then it will take time to realize that here is personally Kṛṣṇa or Śrī Caitanya Mahāprabhu or the ācāryas are present here. It is a question of realization. The more you strictly follow the regulative principles, chant sixteen rounds regularly, the more you'll realize.
Because God, Kṛṣṇa, is omnipotent. He can accept your service. He can bless you even from the picture. That is God's potency."
