The Padmavati Yakshini Mantra Sadhana should be commenced of the Trayodashi Tithi [the thirteenth day] of the Hindu Month of Kartik and continued until the Shukla Pratipada [first day of the bright half of the lunar Month]
During this period, the Sadhaka should chant the Padmavati Yakshini Mantra shown below 1000 times daily. Any kind of counting rosary should be used to keep track of the number of Mantra Chants.
If the Sadhaka succeeds in the Mantra Sadhana and is successful in invoking the Padmavati Yakshini, she blesses him with all kinds of material, including food of all kind, dry fruits, milk, flowers and material for performing any kind of Puja or Mantra-Yantra-Tantra Experiment. The Padmavati Yakshini also stays with the Sadhaka like a faithful helper and performs tasks for him and on his behalf.
ॐ नमो धरणीन्द्रे पद्मावति आगच्छगच्छ कार्य कुरु कुरु, जहाँ भेजू वहां जाओ, जो मंगाऊ आन देवो न आन देवो तो श्री पार्श्वनाथ की आन सत्मेव कुरु कुरु स्वाहा ||
Om Namo Dharnindre Padmavati Aagachhagachha Karya Kuru Kuru, Jahan Bhejoo Vahan Jaa-ao, Jo Mangaaun Aan Devo Na Aan Devo To Shri Parshvanatha Ki Aan Satyameva Kuru Kuru Swaha ||
