if there is no conflictiong words in the mantram that might carry wrong sense, there is no great mistake in chanting that on a different occasion.

The sankalpam ( the formal declaration in ornate Sanskrit about what we plan to do as a religious ritual) and the vedic riks (mantras or quotes) we chant are just like fillers of time while performing the ritual with something divine.. a vedic mantra.. or a few nice words in Sanskrit..

We have to take care not to chant mantrams without understanding what we do because we are likely to deliver the wrong meaning and sense..

And that can make us look like fools before any knowledgeable audience..

Here thereis hardly any such problem,, because no one knows what he is doing.. ..

The mantras from Vedas, and the ritualistic slokas have been quoted and transposed by various people to various other rituals and for various purposes too.

And the original context of the mantras and chants either doing tarpanam to pitrus or doing harati to god has very little in common..

So, if there is no conflictiong words in the mantram that might carry wrong sense, there is no great mistake in chanting that on a different occasion.. and in the way one has known and learnt

The old teachers made a fuss about verbatim reproduction only because they had a chance to control the people in general with threats if there is even minor variation..

This tendency is manifest not only which practicing rituals in Hinduism, but that sort of rigidity is there in every religion..

The general rule is that we should worship god with heart and mind pure, body pure.. and the worship should be a matter between the devotee and the deity..

Often we tend to make fuss about minor procedural matters..

That is not necessary.

In fact, I posted a few vedic mantras only because I had posted them in manuscript earlier and many were not able to discern my bad handwriting..

So I processed the material in legible words in the word processor..

That is all.. There could be even unexpected spelling errors..

I am not an authority on anything.. I am nowhere near perfection.

I am just a wayfarer, a traveller..

I just share a little from what I read and experience from my journey of curiosity. and in my own way.. and my presentation is limited to what I know, what I understood, and such knowledge is faulty, incomplete..

I never ask anyone to follow anything..

And if and when I do a pooja( formal prayer and worship session) , it is just a private matter between me and my God..

And in a pooja only two need bother..

The worshipper and the worshipped.

Others have little role.
