Lama Zopa Rinpoche commented, "In U-Tsang, a famine happened and so many people died, he [Thangtong Gyalpo] made a prayer in front of the Jowo in Lhasa. Then, those people whose mind was purified, they saw Chenrezig pouring grain, seeds, from the sky. So much happened in the country where the famine happened, so the famine completely stopped. It seems from that time a famine didn’t happen." Mahasiddha Thangtong Gyalpo was a great yogi of fifteenth-century Tibet. In addition, he was a skilled engineer and artist, famous for helping the people of Tibet in very practical ways. He is said to have built fifty-eight iron bridges, sixty wooden bridges, 118 ferry crossings, 120 assembly halls and temples, 111 stupas, and many hundreds of large and small statues, and created innumerable paintings. 2020 edition.
