singing his praises...

The next is singing his praises.
Singing his various names and famous deeds from the heart is what it involves. If it can be melodious it is good for others :-) If not, it is good for the singer! The involvement of heart is what is important. As one keeps singing the mind gets near the Lord more and more. Exemplary satakas who followed this way are meera, aandal, soordas, the alwars, the and nayanamars. Count less other people have also followed this way. Actually no bhakta can ignore this way. Does not matter what the form of Lord one relates to, he has said that recite my names and that will please me.
When a group of people get together and do this, there is a satsang. The members of a satsang draw strength from each other and the bhakti will get firm.
The spiritual leader who did gave so much of importance tot his technique and spread it is Srimat Bhodendra Saraswati. Brahmanda purana says no one needs any instructions to do Hari sankeertan. There is nothing superior to it.

ஹரி சங்கீர்தனஸ்யாஸ்ய நோபதேச: கதஞ்சன
when the mahabharata war ended Krishna told Dharmaputra, “Go and get instructions fro Bheeshma who is in the bed of arrows, waiting for his death. There are few persons with his knowledge of Dharma and there is no one more qualified to give instructions on that subject.”
So he went ahead and a lively discussion ensued. After thrashing pout several points Dharmaputra asked, ”which dharma is the best of them all?”
Bheeshma replied, “ what is to be told is superior to all other dharmas. If one will sing the praises of the vasudeva who resides in the lotus of heart with most devotion always – that is the most superior.
"கோதர்ம: ஸர்வ தர்மாணாம் பரம பவத: மத:?
“ [எந்த தர்மம் எல்லாவற்றிலும் உயர்ந்ததாக கருதப்படுகிறது?]
அதுக்கு பீஷ்மர் சொன்னார்:
"ஏஷ மே ஸர்வ தர்மாணாம் தர்மோதிகதமோ மத:
யத் பக்த்யா புண்டரீகாக்ஷம் ஸ்தவைர் அர்சேத் நரஸ்ஸதா"

Why is this considered so great?
Mainly because it does not cause any harm to anyone. (I can hear somebody say that it depends on those who listen to it! :) One need not even pick a flower. Or pick fruits to do “nivedanam”. One need not try and procure anything for that matter.
It does not require any qualification. Anyone can do it; whether you are male, female, adult. Child... there is no restriction. Caste is not a restriction. There is no restriction of the place. Night or day – it does not matter. There is no restriction as to the order. In short NO RESTRICTIONS!
But it is said that nama sankeertan will put in hell those who abuse it!
So what is the abuse?....
