A well meaning beginner sadhaka recently approached me saying they are doing Ganapati Sadhana ( plus 5 other mantra sadhanas ) and not experiencing any results.
I asked if they had asked their Guru who gave them initiation ( which should always be the 1st person you go to ) , and they said they were not always available due to ill health.
As person was in the same Parampara and Sampradaya as me, and i had done the same Sadhana with success, i adviced. They showed me their elephant ivory tusk mala ( which costs upward of $10,000 usd in western countries ) and asked if it would aid siddhi.
Then some rare meteorite stones (im not kidding) and asked how it could be used for Sadhana.
Then their beautiful Panchaloha Murti of Ganapati, which they do puja once a week. Then showed me a Yantra of Ganapati (with Bijas) that they had also acquired.
All of that and i asked how much Japa they had done. 9000.
Do they do minimum daily puja for Ganapati? No.
How do they do japa? is it on a constant time each day on proper asana, at least 500 a day? No.
They sit on their sofa and do it, as and when, with no proper schedule.
