Jayantakrid das: 

I remember Prabhupada in our small temple in Switzerland. At one time he gave a class, and he was describing how we should create a very nice singhasan in our heart and invite Krishna there and it should be as beautiful as we can. It can be in gold, it can be in jewels, diamond, and we should seat Him there and worship Him.
