Remembrance of Krishna is not possible for the impure soul who has not practiced Krishna consciousness in devotional service. Therefore, one should practice Krishna consciousness from the very beginning of life. If one wants to achieve success at the end of his life, the process of remembering Krishna is essential. Therefore, one should constantly, incessantly chant the Maha-Mantra — Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama Hare Rama Rama Rama Hare Hare. — Bhagavad Gita As it is, 08.05.
Even a small service performed with love & devotion pleases Lord Krishna.
The Lord does not accept anything offered by those who do not chant one hundred thousand names of the Lord each day.
Where there is discussion about Hari, that is a place of pilgrimage.
This is the symptom of a pure devotee. One should serve the spiritual master first. It is not that one should bypass the spiritual master and desire to serve the Supreme Lord.This is not the Principle for a Vaishnava. — Srimad Bhagavatam, 07.09.28.
The spirit soul is ever fresh. He is always different from the material body & mind is always subject to disturbances.
Surrender fully unto the lotus feet of the Lord. That is the only business of the perfect human being.
Srimad Bhagavatam 1.5.20,
Krishna does not agree to award devotional service to merely anyone. Krishna can easily offer a person material happiness or even liberation, but He does not agree very easily to award a person engagement in his devotional service. Devotional service can in fact be attained only through the mercy of a pure devotee. — The Nectar of Devotion, Page 14.
Total absorption in hearing Sankirtana Music develops faith in Lord Krishna.
