Giriraj Swami read and spoke from Sri Caitanya-caritamrta, Madhya 9.178 – 194.
“Srila Prabhupada raised the question, ‘Why do we call this building a temple and that building, an ordinary houses?’ He said, ‘In this house, we are living. And the next house, they are also living. So what is the difference? The difference is that here, Krishna is the center. Therefore it is temple. And next door, a house. That is the difference between house, ordinary house, and temple. This is also made of bricks and stones and wood, and that is also made of bricks and stones. They also live, they also cook, they also eat. Everything is the same, practically. But the difference is that there is no Krishna, and here is Krishna. That is the difference.” The temple is spiritual because everything is engaged in the service of the Lord. Even the physical body when fully engaged in the service of the Lord becomes spiritual. When we engage them in the service of the Lord, material things become spiritual. And conversely, if we want to use something spiritual which is meant for the service of the Lord—which is really everything that exists—for our sense gratification, it becomes material. So, Ravana kidnapped Sitadevi to enjoy her, but he didn’t get the spiritual Sita; he got the maya Sita.”
