Take some milk in a cup. While gazing at the milk, repeat the following mantra twenty-one times and thereafter drink the milk. This is an excellent aid to Brahmacharya. This Mantra is worth remembering by heart.
" ॐ नमो भगवते महाबले पराक्रमाय मनोभिलाषितं मनः सतंभ कुरु कुरु स्वाहा "
Om Namo Bhagavate Mahabale Parakramay manobhilashhitam Manah Satambh Kuru Kuru Svaha .
- From Youvan Suraksha
