4. Trái tim tôi đã đến đó trước! Người đàn ông nọ quyết định thực hiện một chuyến hành hương đến một ngôi đền trên đỉnh Himalaya vào mùa đông. Bất chấp thời tiết lạnh giá, ông vẫn kiên trì thực hiện chuyến đi của mình. Trên đường đi, ông gặp một người khách bộ hành khác. Hai người vừa đi vừa trò chuyện. Sau khi nghe mục đích chuyến đi của ông, người kia can ngăn: - Anh bạn ơi! Làm sao anh có thể đến được ngôi đền ấy trong thời tiết giá lạnh như thế này? Người hành hương nhìn người bộ hành rồi vui vẻ trả lời: - Không đâu anh bạn ạ! Tôi sẽ đến được đó rất dễ dàng vì trái tim tôi đã đến đó trước rồi!
