Near the end of sadhana? What do you mean?
Its a bit complicated but I will try to explain what I have learnt from my elders.
Bhakti can be divided in 9 progressive steps
1) Sraddha
To even reach this stage is a direct result of pious credits in previous birth. When a fortunate soul, due to the grace of the Vaishnavs, gains faith (or
Sraddha) towards Lord Vishnu and His devotees, and the message of the Scriptures, that person has reached this stage.
2) Sadhu Sanga
Due to their faith, the devotee will begin to associate with Vaishnavs as per their attraction towards a form of the Lord. They will learn from Vaishnavs, and among them accept a Guru, who will merciful give the disciple the Holy Name.
3) Bhajan Kriya
During this stage the devotee begins the process of Sadhana (spiritual practice). In accordance with the rules of scripture, they will chant the Holy Name of the Lord and perform the 9 limbs of Bhakti. During this stage the devotee is purified of all his previous Karma and His spiritual form begins to form.
4) Anartha Nivritthi
This is the longest phase. After ardent spiritual practice (or by the mercy of the Lord and His devotees), the
anarthas or the defects covering the soul are slowly removed. When these
anarthas are removed, the form of the Lord slowly rises in their heart (when chanting the Holy Name, the devotee should see the Form of Krsna directly).
5) Nishta
At this stage, because the devotee is seeing the form, they chant constantly.
Nistha means steadfastness, and at this stage the devotee is steadfast in Bhakti.
6) Ruci
At this stage, the qualities of Krsna arise in ones heart. Due to the influence of the Holy Name, one can realize the qualities of Krsna, one can even hear His divine voice.
7) Ashakti
ashakti means detachment, and at this stage the devotee begins to see the pastimes of the Lord, which appear to them as they chant the Holy Name. They become totally distanced from the material world.
8) Bhava
In this stage the devotee tastes a drop of
Prema (love for Krsna). Not only do they see the pastimes, but the Holy Name reveals to them their spiritual body, and the mood under which they are serving Krsna. When this body develops, the devotee can enter into the spiritual world while at the same time remaining in the material world. This is the highest stage attainable in the material world.
9) Prema
Finally Divine Love for Krsna manifests and the devotee enters into the spiritual world to eternally serve the Lord and His associates.
As you can see, ones spiritual form and mood is officially revealed in a very late stage of
Bhava, but according to the Lord's Will, you will generally associate and again attraction to the school of Vaishnav philosophy as per your mood. If your eternal service is towards Lord Rama, then you will be attracted to the Ramanandi Sampradaya. If you are eternally worshiping Lord Narayana in Vaikuntha, then you will be attracted to the Sri or Madhva Sampradaya etc.
I apologise if this is too personal of a question, but how did you meet your gurudeva?
I met my Gurudev hmmm about I'd say 8 years ago. Actually I was deeply attracted to the Gaudiya Sampradaya from very young but all the great personalities had already left the earth at the time. I was attracted quite alot to Srila Bhaktivedanta Narayan Maharaj and Srila Gour Govinda Swami, but they both had left their bodies earlier. I always prayed to Lord Nitaai Gaur and Radha Krsna to please send a personality whom I can take Shelter of. Of course, Nitaai is very merciful and I soon met my Gurudev. He accepted open heartily. My Gurudev was always a very online person so it was easy to find him and after associating with him for a few years, it confirmed He was a genuine Vaishnav. He never criticized anyone for any reason and was deeply knowledgeable about scripture. When he would since Kirtan, tears would appear in my eyes just from hearing the sound vibrations. I always remember His one of his first instructions to me "Always we humble, think yourself lower than a blade of grass, because this is the one quality that attracts God.". My Gurudev at that time was heavily preaching the glories of Lord Nityananda and Gauranga to the Gaudiya community. I mean if you look at his Youtube channel, he has uploaded like 2000+ videos of his lectures and talks over his years, from 7 day lectures on Srimad Bhagavatam, to talks on more confidential books like Navadwip Dhama Mahatmya. It was only in 2012 in Ekachakra that Lord Nitaai gave Him the order to preach and start the Nitaai Mission and he has been doing it ever since. .
