Born in Teplik, Ukraine, he became active in the Breslover community in nearby Uman, where he married the sister of Abraham Chazan. Chazan's father, Nachman Chazan, was the closest disciple of Reb Noson, who was in turn the closest disciple of Rebbe Nachman of Breslov.
Breslover leaders of the following generation, such as Rabbis Shmuel Horowitz and Yitzchok Gelbach, attributed their initial interest in Breslov teachings to their first exposure to Alter Tepliker's Hishtafchut HaNefesh.
Tepliker pioneered the publication of Breslover teachings on specific topics. His ten books include:
- Hishtafchut HaNefesh (Outpouring of the Soul) — on the topic of hitbodedut (meditation)
- Meshivat Nefesh (Restore My Soul) — on the topic of inner strength
- Or Zorei'ach Haggadah (The Breslov Haggadah) — on the Passover Haggadah
- A commentary on Pirkey Avot
- Mei HaNachal (Waters of the River) — a commentary on Rebbe Nachman's Likutey Moharan.
