Ganesha Mantras
Beejakshara mantra
Sri Ganapati is the elephant headed son of Sri Shiva, belonging to the divine family that delivers the soul from darkness and sin, the specific function of Sri Ganapati is to teach and drive away ignorance (avidhya). He is represented by Ketu, the significator of emancipation from all kinds of bondage including rebirth.
The Beejakshara of Sri Ganapati is ‘gaM’
Bīja mantra: गं (gaṁ) which is also called the Gītā bīja (for Srimad Bhagavat Gītā) by those learned in mantra śāstra. This is the starter of everything and just like the Bhagavat Gītā, provides the power to assimilate all knowledge.
Tantrika bīja (physical abilities and strength): गङ्ग् (gaṅg) which sounds like Gaṅga
Vidya-Siddhi Mantra
The fourth house rules education and learning. Any affliction coming on this houses causes loss of learning, breaks in education and the mind has problems in focusing on studies. This phenomena is marked in children between 3 to 12 years of age due to the natural impact of Mercury (Naisargika dasa). This is caused due to the shad-ripu or the six flaws that cause tamas guna to prevail. A mantra that removes the energies from the sixth house and places them at the fourth house will help in rectifying the problem. One such mantra is given below as it has six words (sixth house energies removed) and sixteen syllables (fourth house spiritual energy added).
Siddha Mantra: नमो गणपते तुभ्यं ज्येष्ठज्येष्ठाय ते नमः
namo gaṇapate tubhyaṁ jyeṣṭhajyeṣṭhāya te namaḥ
This mantra is fully protected on both sides, a technical term called saṁpuṭa, by the word नम (nama). This word is means obeisances or bowing with complete humility and is of neuter (napunsaka) gender. The mantra brings humility in children and they learn to bow to the teacher, elders, books and the knowledge. Just as water flows from a higher level to a lower level, so also the knowledge and good qualities will flow from a head in the higher level to the bowing head at a lower level.
Karya Siddhi Mantra
How many times have you said or heard ‘if only I had persisted’ or ‘I should have been stronger’? Strength of mind and body to achieve is a rare gift seen in the great achievers. This is called Parakrama bala or the ability to drive themselves towards the goal and become great men.
The third house has the energies that can be used for sexual activity (in fact the third house is called maithuna bhava implying sexual union), fighting or any physical action. The fifth house is the seat of the thought that causes this action and the tenth house indicates the action itself. A mantra that takes the energies of the third house to the tenth (or other) house is the best for daily practice as it reduces the sexuality and bestiality in men helping them to focus better on the work at hand. The following is a three word (takes energy from the third house), ten syllable (deposits the spiritual energy into the tenth house) mantra where the deity sits in the fifth house. This mantra finds mention in the Mahā Nārāyaṇa Upaniṣad.
Siddha Mantra: ॐ महागणपतये नमः
om mahāgaṇapataye namaḥ
Labha-Siddhi mantra
If every thought which is the seed for action is successfully concluded, we would be the happiest people in the world. Alas this does not happen and we are left wondering as to the cause of the obstruction and spend money, material and other resources trying to achieve the objective.
A mantra that takes the energies of the fifth house to the eleventh house would be the best as it converts the knowledge (fifth house) to gains (eleventh house). Such a delightful mantra that helps us to achieve objectives is given in the Shiva Purana. It is said that Ganesha has two śaktī – (1) Siddhi devī giving all abilities and accomplishments and (2) Buddhi devī – giving supreme intelligence and sharp mind. They have two children (1) Lakṣa (goal attainment) which comes from Siddhi and (2) Lābha (gains of hopes and desires) which comes from Buddhi devī. Both these objectives are in the 10th (Lakṣa) and 11th (Lābha) houses. In the natural zodiac these houses are ruled by Saturn – Capricorn and Aquarius, making them difficult to achieve due to various weaknesses that people possess. This mantra removes the ills of Saturn that plague mankind and makes the sādhaka very competent and brilliant. It is strongly recommended if Saturn is either ātmakāraka or aspects the Lagna (or Lagneśa) in the chart. No doubt that the Śiva Purāṇa gives much emphasis to this mantra.
Purāṇa Mantra: ॐ लक्षलाभयुताय सिद्धि-बुद्धि-सहिताय गणपतये नमः
om lakṣalābhayutāya siddhi-buddhi-sahitāya gaṇapataye namaḥ
