The disciple who wants to have initiation into mantras should approach a Guru. He can very well make enquiries about his proposed Guru, before going to him. Then, Guru will test his proposed disciple. No Guru will initiate mantras on the first day. He will watch the qualities of his disciple. Once he is satisfied, Guru will decide which mantra will be initiated to his disciple. They both will have discussion on the mantra. Then an auspicious day will be fixed. Rohini, Ardhra, Punarvasu, Pushya, Magha, Jyeshta, Mula, Utharashada, Shravana, Sravishta, Utharabadhrapadha and Revathi are considered as the best asterisms. Chathurthi, Ashtami and New moon (amavasya) days to be avoided. Tuesdays should be avoided. At the time of initiation, the lagna should be in movable sign. 8th house from lagna should be vacant. Pithur masas like ashada, Badhrapadha, margasira and maga months should be avoided. The disciple’s birth star, 10th and 19th from his birth star are auspicious. Sun’s transit from one rasi to another rasi is very auspicious. Wednesdays and Thursdays are good. Having thus fixed the day of initiation, the disciple will go to the place of his Guru with fruits, flowers etc. well before the appointed time. The process will start with prayers to Mahaganapathi. Most of the learned Gurus first initiate a Ganapathi mantra. Only then other mantras are initiated. After prayers to Mahaganapathi, prayers are offered to ashtadik balagas and navagrahas. Then Guru will perform punyakavachanam by invoking lord varuna and this water is sprinked on the disciple. Then Guru will give a small talk about the deity, whose mantra is to be initiated. Then the disciple will asked to sit facing the eastern direction and the Guru will sit facing the northern direction.
Nobody will be allowed anywhere near the place where Guru and his disciple are sitting. Then Guru will start saying the mantra very slowly asking the disciple to repeat. Thus Guru says the mantra three times and the disciple also repeats three times. After this process Guru also informs his disciple, about his (Guru) guru from whom he got his initiation. This lineage is called Guru parampara. Then other details of the mantra like dyana sloka, nyasa etc are taught. Then the disciple should pay respects to his Guru and please him dakshina etc. The disciple should go to his Guru on the next day for repeation of the mantra by Guru. This process is called dwithiam. Incase of any mistakes that could have happened on the first day inadvertently, will be rectified during this process. The After this process, the disciple should start doing japa daily, both in the morning and evening. The counts should be fixed and should not vary, at least should not be reduced. The number of japas of each mantra has been fixed by ancient rishis. Let us say that some has got 2,00,000 japas. Once, that much amount of japa is done, Guru is to be informed. After his permission and as per his directions, puracharana is to be performed. This consists of 10% of the japa as Havana and 10% of Havana as tarpana and 10% of tarpana as marjana and 10% of marjana as bhojana. For 2,00,000 japas, ahuthis of Havana will be 20,000, tarpana will 2,000, marjana will be 200 and bhojana to 20 people. After performing this, the disciple will attain siddhi in the mantra. Whether mantra siddhi is attained or not can be said only by the Guru who has initiated the mantra. This is the concluding part of the mantras.
