Efficacy of chanting Lord’s Name

Namasankeertana is the best and good method of reaching self-motivation and spiritual guidance towards God.   Chanting the name and glory of the almighty with devotion, dedication and discipline, the devotee gets peacefulness to mind and body.  By chanting God’s name with dedication one can surrender himself to God and lead to Bhakthi Path.
With the Lord’s name in mind and soul, we can reach his heart. Give yourself to God every opportunity you get, and he will fulfill all your desires.

There are no restrictions (niyamas) for chanting the Lord's name. Neither must one take consideration of the time or circumstances; all you need is full dedication to him.  When chanting God’s name, one need not observe Pranayama, Anganyasa, Karanyasa, Bhuta Sudhi etc.
‘Manthra’ is a Sanskrit word, ‘Man’ means “mind” and ‘thra’ means “to deliver”.  Thus a ‘Manthra’ will finally leads you to spirituality of mind and body. It is echo of sounds from your inner self.
If you cannot chant Manthra always, you can repeat the Lord’s name in whatever way you call him and Pray him (ex. Rama, Krishna, Govinda, Hari, Mahadeva, Muruga, Ambige etc.).  But you must realize in the heart, the ‘Name’ and the ‘Manthra’ has same power.  The most important thing is concentration which you should have in your heart and mind.
Your tongue should proclaim the great Manthra or the Name even while you are eating, sleeping, standing or sitting.  Do it and you will find great pleasure and happiness.  If you find time, go to a quiet place, sit and chant the name. You will find your heart’s treasure in front of your eyes and everywhere.
When we sing the name of the Lord, our mind should dwell only on the thoughts of the Lord.   By doing so we derive ultimate joy.  There is no other tool like “Namasmaranam” which gives peacefulness to mind and body.
Chanting the sacred name of God starts from beginning of the evolution of earth.  According to Hindu mythology all the things are created and contained in the voice of "aum".  Describing the glory of God by chanting his different names is followed in Hindu religion.  
Everyone knows life requires good health.  Proper diet, adequate exercise, and sufficient rest are necessary to keep our bodies strong and fit.  If we neglect these things, we become weak.  If we ignore our spirituality we tend to acquire other unnecessary qualities.
Kali-yuga is an ocean of faults, but we can rectify it simply by chanting Lord’s names.  One can become free from all difficulties of life and find his way to the Lord’s feet.
The ‘Upanishad’ instructs us as follows: "The Hare Krishna maha-mantra, composed of 16 names and 32 syllables, is the only means to counteract the evil-effects of Kali-yuga.  In all the ‘Vedas’ it has been proved there is no alternative to chanting of the Lord's holy names to overcome the difficulties of the life."
In Ramayana  replete with drama and poetry, the epic is soul-stirring with the hero — God (Lord Rama)  in human garb, exemplifying a person who should raise himself to a perfect level through his efforts.  He serves as a role model for the entire world.  A disciplinarian and a leader, Rama never compromised in upholding the Law of Virtue.
That even the very utterance of His name, as He is a replica of Dharma, can cure us of all ills is revealed in a story concerning Saint Kabir, a herbalist too.   In Kabir’s absence, his son once prescribed a dose of basil water and the chanting of Rama's name thrice to a patient. Coming back to thank as he became all right he was aghast to see Kabir thrashing his son. What made Kabir angry was that his son had advised the patient to chant Rama's name thrice, when just chanting the Lord's name once would have served the purpose.
Such is the effect of Rama Nama and we all will chant the Lord’s name and attain peacefulness in our life.
