Kisvei Rebbe Yisroel is a collection of letters from both Rebbe Yisroel Dov Odesser and Rebbe Yisroel "Karduner" Halpern. Rebbe Yisroel Karduner was a 4th generation Breslov chassid in an unbroken chain of rabbi to student back to Rebbe Nachman. He later became the Rav of Rebbe Yisroel Odessers. A strong bond formed between the two Yisroel's as both rav and student progressed in their goal to draw closer to Hashem and spread the light of Rebbe Nachman. The letters in this compilation are a great source for words of advice and encouragement.
