Keeping a keris for protection

[Pusaka]

"If possible, the consecration of the jimats through the mantras is best when completed either on the new moon, full moon or a particularly auspicious day called Kajeng Kliwon that occurs every fifteen days. Consecration proceeds as follows:

1. Bringing the jimats into being with its accompanying mantra, using the name of the recipient as well as visualization
2. making the jimats alive with the Penguripmantra,
3. following with a joining mantra,
4. concluding with the Pasupati mantra that imbues the jimats with sakti

The jimats is then worn next to the skin by the recipient, who is instructed with additional information on the responsibilities of honoring, respecting and maintaining the live state of the jimats. If these instructions are not followed the jimats will cease to contain living energy."


Above was what I was referring to, the isi (or whatever you prefer to call it) would be created in a similar way. Also its questionable as to whether a keris was made for one person or not. That is why some would prefer a new keris rather than an old one
