There is a default tendency in us to expect everything to be comfortable and easy. We expect everything to happen overnight and look forward to enjoy the fruits of spiritual advancement in near future.
When we become really sincere, we understand what we are aiming at is very valuable, we have a lot more to go. We develop confidence in mercy of Lord and potency of devotional service. Then we work hard to pay the price.
In this way, we embrace the challenge of spiritual life.
