Shiva deity of Moskha(Liberation) and Death - Ultimate(Main) GOD(Ishwara/Allah)
There is no other way to fulfil worldly desires unless she visits Shiva Lingam everyday.
There is one Shiva Lingam in Gujarat, which is known as
"Kuber Bhandari", This shiva lingam is known for fulfilling money or financial issues of people. Devotees visit this Great Jyotiswaroop Shiva lingam with true faith, they request Lord to fulfill them with money. It is a strong belief of devotees that
"Kuber Bhandari" is master/owner of all money on earth. So they will be granted some money to be rich in materialized world.
Conclusion is that, one does not need to do meditation to be rich. Happy people are happy rich/poor. One must understand that even after being rich, one is only in charge of whatever they have. Having "Moha" is not good. But one if with true faith, requests GOD without "Moha", wishes are always fulfilled.
Better is let her go with western style meditation. She does not need GOD, she needs money only. So it is best to give her freedom whatever she feels is right. Meditation has nothing to do with materialized things. Meditation is for soul's peace, not for body.
If she choose to be with Hindu
Prayers are Om Namah Shivaya Dhun, by sitting exactly in front of Shiva Lingam, sitting should be comfortable enough. Because one needs to forget body while meditation.
Other prayers are,
- Shiva 1000 names (Shiva Sahstra Namavali),
- Vishnu Sahastra Namavali and
- Gayatri Mantra Dhun.
- Shiva mahimna strotra
- Om namah shivay dhun
All of them are available on You Tube. Download or play them when you sit in meditation, if you feel it is good to your heart.
Sadhana requires concentration, any music that increase your concentration is good while meditation BUT DO NOT GIVE ATTENTION TO MUSIC WHILE MEDITATION.
The most effective in daily meditation according to me is "Om Namah Shivaya Dhun".
Disclaimer: This prayers are chosen by me, they are not standardized ones. One can choose what one's heart feels good. This is my personal opinion based answer just to help questioner.
Prayer to GODDESS महालक्ष्मि
One can also seek money and get fulfillment by praying or chanting GODDESS महालक्ष्मि prayers.
महालक्ष्मि अष्टकं Verse 10
एककाले पठेन्नित्यं महापापविनाशनम् ।
द्विकालं यः पठेन्नित्यं धनधान्यसमन्वितः ॥१०॥
10.1: Reciting this Once Every Day will Destroy Great Sins,
10.2: Reciting this Twice Every Day will bestow one with Wealth and Foodgrains.
So if you chant this prayer 2 times, morning and evening, it is written over here that you will be granted with wealth.
This one was important for your friend. Ask her to chant this prayer at morning and evening, 2 times a day. And check her status whether she gets wealth or not.
In shani chalisa, it says if you do this prayer on Saturday, "Lakshmi Gruh Ave" means money comes to your door.
If you perform fire rituals, it is given in Vedas that one will have money issues solved.
