Hello,
Thank you for reaching out. We are the admins of the website Thay Thich Truc Thai Minh!
Your question has been answered by Thay:
"When our body enters the state of deep meditation, it becomes very special, it doesn’t consume much energy. Even your breath seems almost non-existent but it doesn’t mean that our body is dead. That is a special thing in the state of meditation. This is a truth that many zen monks have experienced. It may sound impossible and strange to many people but we — Buddhist practitioners — do believe this is the truth. I myself do sitting meditation for six to seven hours, I feel like time flies very quickly. This requires your practice and gradually your ability will increase."
If you have any more questions, please let us know.
We wish you and your family peace and happiness!
