Sincerity in sadhana and eagerness to serve is the basis of one’s relationship with the spiritual master.
There is no greater achievement that anyone can ever acquire than the opportunity to serve.
We should not expect others to love us. We should try to give Prabhupada’s love to others. That is Service.
What assurance of real happiness is there in all of one's wealth, youthfulness, sons and family members? This life is tottering like a drop of water on a lotus petal. Therefore you should always serve and worship the lotus feet of Lord Krishna.
One can attain the path of liberation from material bondage only by rendering service to highly advanced spiritual personalities.
In our conditional stage, we cannot worship Radha and Krishna. Radha-Krishna-seva is for them who have developed spontaneous love for God.
