Upon witnessing the power of pure love, your heart will experience a sense of gratitude, which will form the foundation for pure devotional service, a foundation which will remain strong enough to withstand the tests of illusion.

Just as a person wanting to increase his wealth invests his own money for getting more money in return, in the same way, one who has some faith must invest his faith in someone who can help to increase his faith.
Collected Letters to Friends and disciples Vol 4, Pg 121
The deeper the spiritual experience we get from serving and chanting, the deeper our gratitude becomes, and with that, the desire to reciprocate by our service with those who are inspiring us to chant. We must always look to deepen this experience, and that happens by serving those who help us to increase our faith in the holy name.

Chanting should be performed with some feeling. Whether the emotion is hankering for Krishna, remorse, repentance, eagerness to chant more attentively, remembrance of our favorite pastime, or whatever, when there is some feeling, our chanting becomes less mechanical and more spontaneous. Try to capture these moments of chanting with feeling, and take note of what you were thinking about when the feeling came to you.

When we accept some austerity for pleasing Krishna's pure devotee, the return we get is incalculable. So please catch up this spirit and tax your brains to find the means to distribute as many of Srila Prabhupada's books as possible during the upcoming month, and be assured, Srila Prabhupada will smile from watching your endeavors.
Collected Letters to Friends and disciples Vol 4, Pg 115
Thank you very much for your efforts to find novel means for distributing Srila Prabhupada's books. Spiritual life is not stagnant. Its nature is ever-expanding. If, for whatever reason, there are obstacles for distributing Srila Prabhupada's books one way, then there are so many other ways to distribute Srila Prabhupada's books by which anyone can take part.

You have tried to turn away from Krishna, but you still have not succeeded because you have not turned away from me. I am not Krishna. But I am meant to represent Krishna. Therefore, please do not turn away from me, and then together, when you try to help me, we will keep you turning towards Krishna, even though you desire marriage, family, career, and money.

Whenever devotees are driving long distances, the first thing I say when I learn of this is, "Don't drive during the night!!! Stop and rest no later than 11:00 pm. If it costs money to stop and rest, then spend it!!! Everyone should sleep at night so that there are other devotees always awake in the vehicle while the vehicle is being driven. Not that somebody drives and everyone else sleeps!"
Collected Letters to Friends and disciples Vol 4, Pg 24
I am a 100% fanatic when it comes to this point about driving during the night. We have lost so many devotees by this careless mode of passion. It is the responsibility of temple leaders to stop this madness whenever it is noticed!

Through humble service and prayer, you will some day be allowed to serve in a greater capacity and the service will be accepted. But if there is pride and no attempt to curb it, nobody is inclined to accept such service.
