One should not be impatient in Krsna consciousness. Indeed, this Krsna consciousness movement was started single-handedly, and in the beginning there was no response, but because we continued to execute our devotional activities with patience, people gradually began to understand the importance of this movement, and now they are eagerly participating. One should not be impatient in discharging devotional service but should take instructions from the spiritual master and execute them with patience, depending on the mercy of guru and Krsna. The successful execution of Krsna conscious activities requires both patience and confidence.
