Sri Nama Mahatmya - Saranagati - Srila Bhaktivinoda Thakura:
isat vikasi’ punah, dekhay nija-rupa-guna,
citta hari’ loya krsna-pas
purna vikasita hoiya, braje more jaya loiya,
dekhay more swarupa-vilas
more siddha-deha diya, krsna-pase rakhe giya,
e dehera kore sarva-nas
"When the name is EVEN SLIGHTLY manifested He reveals His own divine form and qualities and reveals my own spiritual form and characteristics. It steals my mind and takes it to Krsna's side.
Being fully manifest, the holy name takes me to Vraja and reveals to me His own love dalliance.
He gives to me my own divine, eternal body, keeps me near Krsna and completely destroys this mortal frame of mine."
Srila Bhaktivinoda received and gave Siddha Pranali.
However, in his book Bhajana Rahasya and Saranagati, Srila Bhaktivinoda Thakura teaches that Siddha Deha is also revealed by the grace of Sri Nama Prabhu.
So, Srila Bhaktivinoda Thakura wrote Bhajana Rahasya and Saranagati and didn't follow to the letter the Smarana Paddhati of Dyanacandra Goswami (Siddha Pranali). Leaving the two processes as authentic, i.e. via Diksa Guru an via Maha Mantra.
Indeed, Siddha Deha can be given by Diksa Guru, Siddha Deha can be given by Siksa Guru, Siddha Deha can be given by ascended Guru, Siddha Deha can be given by Nitya Parisada and Siddha Deha can be given by Maha Mantra.
The most important factor is Lobha. INTENSE greed. When this Loba awakens, the Sadhaka begins to meditate on his Siddha Deha, following one of the 5 guides mentioned above.
Before Suddha Nama you'll meditate on your Siddha Deha and you'll know about the particulars of it because of INTENSE Lobha. Even Nama Bhasa has immense power.
