Question: What should I do if there are no auspicious signs of reaching Pure Land, after a relative passed away a year ago? I chanted all the mantras that I knew.
Answer: Without clear auspicious signs of having reached Pure Land, if one has passed away, especially for way beyond 49 days, what more with no sign of the person possibly still being around as an unseen being, the person is likely to be reborn elsewhere already.
Having multiple chants is not what determines reaching of Pure Land. It is the offering of clear guidance (and merits) for reaching Pure Land by the streamlined choice of chants that helps, as can be seen at http://purelanders.com/2013/11/07/how-to-share-the-power-of-merits-guidance
However, even if the one is long deceased, the following can still be practised regularly till one has peace of mind: http://purelanders.com/2016/07/19/what-should-be-chanted-during-after-a-funeral Even though the deceased might not be around to receive guidance to generate the Three Provisions (Faith, Aspiration and Practice) to reach Pure Land, merits shared can still alleviate suffering if born in a less ideal realm, expediting a better rebirth. If the person is able to receive guidance, where he or she is, to generate the Three Provisions, Pure Land can still be reached.
