Purpose of Creation of Human Life
To purify the heart is the one and only purpose that God has created this human life.
Treating Devotees
As you treat a devotee you treat Krishna and accordingly you get results.
Boasting About One’s Service
If you do some wonderful service and if you tell people what you did in a boastful way, it nullifies the credit of your service, may be not in the eternal platform, but in your conscious condition you will not be able to reap the benefits of that service.
Maya
The more big you are the more Maya will utilize you.
Attachment to The Bodily Platform
Compassion without detachment is attachment to the bodily platform.
Difficulties
Difficulties coming from Karma will give us samskaras which will further impel us to perform sinful acts, but difficulties coming from Krishna will purify us.
