Prabhupāda: Yes. This is, this is essential for advancing in spiritual consciousness. Just like kindergarten system, the children are given some wooden, I mean, some plans to form some A, B and C like that, (indistinct). So this not like, exactly like the (indistinct) system. This system is introduced by great ācāryas, authorities. So we have to follow. In the beginning we have no love for Kṛṣṇa, so this process will help how to invoke his love for Kṛṣṇa. This is standard process.
Mohsin Hassan: This is the Vedic philosophy of the ritual.
Prabhupāda: And they are introduced by great ācāryas. You'll find, if you go in India, there are many thousands of temples, the same things are being followed from, since thousands and thousands of years, not only since the time of Kṛṣṇa; before the time of Kṛṣṇa. This is called arcana vidhi, the regulative principles for worshiping the Lord. They are followed. So they, actually Pañca..., this is called Pañcarātrika-vidhi, the regulative principle on the authority of Nārada Pañcarātra. So they must be followed. Otherwise one cannot be purified. This is purificatory process.
Mohsin Hassan: Would you please mention something about the meaning of the ritual of the initiation. They put their hand in the oil and the burning of the fire...
Prabhupāda: They are not putting their hand on the oil. It is called yajña, offering ghee to the fire. This is Vedic, this is Vedic ritual, to offer clarified butter and grains in the fire. Fire is supposed to be the mouth of God. So we are offering eatables to the Supreme Person, rūpa.
