But its being the tip of the iceberg means that it is ice, it is true love. It is not something different. If we can push it to the point of absurdity and say love all beings, it can become very abstract. So actually we don't even feel that warm, losing yourself love ever because it is so dispersed. Like a virtual pet.
All beings becomes like a virtual being.
So we need to keep the human element, the tantric teaching that includes the sacred and the profane and includes our bodies and our feelings and realizes the spiritual through that. That's all love and it functions on a personal level. Like nuns who never married and never had children. They love Baby Jesus. It's using the human tendency, which is part of the iceberg.
