As dalliance with the body in luxury increases, so wanes the spirit of service of the Lord.
Application of humility is service.
We are not here for happy material life, we are here to serve and surrender.
A devotee should always aspire to live in the association of advanced devotees and engage in the service of the Lord through the parampara system.
Real love means service devoted to the welfare of another person, even if the person is inimical towards us. That is the test of love.
When we are physically strong, we engage in service. So that when we are not able to work, we will be able to remember Krishna, Prabhupada, our spiritual master and even our spiritual name in sub-consciousness.
