Pelden Gyeltshen (Wylie: dga' ldan khri pa 40 dpal ldan rgyal mtshan) (1601-1674) was the 40th Ganden Tripa. Early life and education 
Pelden Gyeltshen was born in village Dangkhar, the then capital of the Spiti valley (in present-day Himachal Pradesh, India). Pelden Gyeltsen went to Lhasa for his monastic education, where he studied at Ngari Dratsang and the Gyume College. Monastic career 
Afterwards, he served as a teacher at the Gyume and the Ganden Jangtse colleges, before he was appointed as the 40th Ganden Tripa.
