By pleasing the spiritual master, there are quantifiable results. According to the sastras, when the spiritual master is pleased, Krishna bestows His blessings on the disciple, and we can revive our original Krishna consciousness. In a letter of June 1970, Prabhupada states: “I can assure you that if you follow my instructions as above mentioned there is no doubt about it that through me, my spiritual master, Srila Bhaktisiddhanta Sarasvati Thakura will be pleased, and through His mercy Lord Nityananda will be pleased. In this way, Lord Caitanya and ultimately Radha-Krishna will be pleased, and thus your life will be successful.“
