Srila Prabhupada repeatedly cautioned: "Don't waste time."
Lately I've been looking back at wasted time in my life, and it's renewed my determination to try to follow Srila Prabhupada's instruction.
Time is fleeting. Life is short. What use is my voice when it is not engaged in singing the kirtan of Sri Hari? (publicly in kirtan, or privately in japa)
Don't waste time, foolish mind. Take full shelter of Sri Harinama now.
Every moment spent uselessly now will be regretted later, as we look back on wasted time in our lives. "Vishaya chadiya..." we will lament that we were knowingly drinking poison when we could have been drinking nectar.
Today we are in the prime of our youth, in a human body with the ability to chant. (We could be in a cockroach's body!) We still have energy and enthusiasm. Let us utilize our bodies as an offering to Sri Hari. If we keep ourselves always in the company of the names of Sri Sri Radha-Krishna, while walking, sleeping, cooking, shopping, walking about this world... then Their glory, brilliance, beauty, all-attractiveness will shine through us and we can act as transparent via-mediums, attracting other conditioned souls back to the shelter of Sri Radha and Sri Hari, and His transcendental flute playing.
(Late breaking news: Sri Krishna's flute playing incarnates in this age of Kali as the Hare Krishna Maha-mantra. We can tune into the transcendental sound vibration of Krishna's flute by constantly keeping the sound vibration of the Hare Krishna Maha-mantra on our tongues, in our minds and hearts.)
