Union ministers Nirmala Sitharaman, Nitin Gadkari and Piyush Goyal as also top bureaucrats on Saturday condoled the death of former Finance Minister Arun Jaitley, calling him a mentor and guide for many. Jaitley, 66, died at the All India Institute of Medical Sciences (AIIMS) on Saturday after undergoing treatment at the hospital for the past few weeks. No words can describe the loss of Shri @arunjaitley. A mentor to many of us, a guide and a moral support and strength. Have learnt so much from him. A fine large-hearted person. Always ready to help anyone His intelligence, sagacity, astuteness have no match, Finance Minister Nirmala Sitharaman tweeted. Former finance secretary Hasmukh Adhia described Jaitley as a saint and a true statesman. He was a saint, not a minister. I had the privilege of working so closely with him in four out of five years of his tenure as finance minister of India.He was the best minister I had in my entire career.I am privy to his statesmanship in making the GST a reality. In fact but for him, GST would not have been implemented in a such short period of time, Adhia said. Jaitleys stint in the Modi 1.0 government was affected by his frequent bouts of ill health that even led him to take a short sabbatical. Last year, he took a three-month break to undergo a kidney transplant. Piyush Goyal had filled in for him in the finance ministry at that time. Goyal, who is currently the commerce and industry as well as railways minister, described Jaitleys demise as an irreparable loss.

Minister of State for Finance Anurag Thakur reminisced seeking advice from Jaitley, who taught him the greatest lessons in leadership and humility. Today I have lost the voice that was my conscience, mentor and motivator. I will treasure his early morning discussions and walks; his clarity of thought and his depth of counsel within Parliament outside, he tweeted. Road Transport and Highways Minister Nitin Gadkari said Jaitleys speeches in the Rajya Sabha, both while in power and opposition, will always be remembered.

Economic Affairs Secretary Atanu Chakraborty said Jaitley will be remembered as a great leader and visionary who steered the Indian economy between 2014 and 2019.
