From association with devotees is born faith. From faith is born pure knowledge. From pure knowledge is born meditation. From meditation is born devotional service, which pleases Lord Krishna and destroys all sufferings.
One should not be impatient in discharging devotional service, but should take instructions from the spiritual master and execute them with patience, depending on the mercy of guru and Krishna. The successful execution of Krishna conscious activities requires both patience and confidence.
A pure devotee is the supreme transcendentalist and one has to receive his mercy for one's dormant Krishna Consciousness to be awakened. One has to associate with pure devotees. If one has firm faith in the words of a great soul, pure devotional service will awaken.
The flow of devotional service is so potent that any onlooker also becomes liberated from the influence of the modes of passion and ignorance.
If, by the grace of the Lord and the great-souled devotees of the Lord, a living being becomes fortunate enough to associate with the unadulterated devotees of the Lord and gets a chance to hear the unadulterated glories of the Lord, certainly the flow of devotional service takes place like the flow of a river.
While performing devotional service in the association of pure devotees in full Krishna Consciousness, there are certain things which are required to be vanquished altogether. The most important thing one has to surmount is weakness of the heart. All the problems of material existence are due to these weaknesses of the heart.
