Respected Veer Balbir Singh Ji,
As I said before I may be wrong. I used to wonder about this as well. But then I tried to find out why people say they use it and does it really work. My research boils down to this: it can be used to start, but it works for only those people who have very strong belief in Bani. If they believe only in Numerology, it may bring some material benefits for them as they are the ones who do it more like lip-reading, there is no spiritual uplift of any kind.
There is neither only one religion in this world nor only one belief. So if something works for a person to start on a rightous path, I do not think it is bad. Take the example of Bhagat Dhanna: Guru Sahib has not recomended Murti Puja anywhere, but his mention is there in Dhan Dhan Siri Guru Granth Sahib Ji. We all know that he did stone worship, BUT WITH ONE POINTEDNESS, and was enlightened. Again, I am not recomending stone worship. It all depends how the person percieves things, once he/she is actually starting to follow Guru's teachings.
Take the example of Bhumian chor, he was not ready to stop stealing but he was so truthful to Guru's word and actually did all what Guru Sahib told him to do.
One poitedness is all that matters. Once a person is so lost in what Guru is saying, i tell you nothing else remains. Any body from any religion, one who is a realized person, will not denounce any phylosophy that can put you to a start.
Guru Sahib when talks about ginti ganana and all that, is bewaring us not to get lost into such practices. There are so many people who use the nitnem schedules, how many are the realized souls out of them. Main reason is that they are lost in completing their nitnem everyday, that is all, there is no concentration on what is being read. Exactly same is with number idiology, you get lost in numbers you are lost.
Bani is so powerfull veerji, it turns the toughest around. These numbers and these nitnem styles loose their power once bani reaches into rom rom, provided it is done with one pointedness.
