It is always more than necessary for bhakti-yog to be extremely educated in Gyana-Shastras.
The heart must be cold and compassion-and-emotion-void.
I suppose, that Bhakti-Yoga is not possible without Gyana and especially the awareness of everything being the illusion.
By the way, I also hate the idea of compassion, because it is just sentimental crap.
The following darshan of Shree Shreemad SwamiNarayan is incredible and very Gyana-imbued!
Gadhadã III – 19
Two Undesirable Traits Of A Tyãgi
He was dressed entirely in white clothes. Also, garlands of mogrã and karnikãr were hanging around His neck. A sabhã of munis, as well as haribhaktas from various places, had gathered before Him.
19.2 Then, Shreeji Mahãrãj said, “A bhakta who has abandoned worldly life may possess two negative traits which are not appropriate for him in this satsang; the first is lust and the second is affection for his relatives.
In my eyes, a person who possesses these two negative traits is like an animal. Of these two, I have an extreme repulsion for a person who has excessive affection for his relatives.
19.3 “For this reason, a person who has abandoned worldly life should not keep even the slightest amount of affection for his relatives.
This is because having affection for bodily relatives is a greater sin than the five great sins.
Therefore, a tyãgi bhakta of Bhagvãn should realise his own chaitanya to be distinct from both the body and the relatives of the body.
He should believe, ‘I am the ãtmã; I have no relations at all with anyone’.
In fact, the relatives of this body should be considered together with the relatives of the 8.4 million types of previous life forms.
If a person does try to understand the greatness of his relatives, knowing them to be satsangis, then since there is already some affection due to the fact that they are related, he develops more affection for them than he has for Bhagvãn and the bhaktas of Bhagvãn.
Therefore, if a person does keep affection for his relatives knowing them to be bhaktas of Bhagvãn, towards whom affection is natural, then his life becomes useless.
19.4 “Moreover, it is also natural for a person to develop affection for those who perform his sevã, even though they may not be his relatives.
So, a person who is wise should not keep affection towards a person who is serving him, even if that person happens to be a bhakta of Bhagvãn.
For example, if a snake has released venom into sweetened milk, the mixture also becomes poisonous.
Similarly, out of self-interest, a person should not keep affection towards someone who performs his sevã, even if the person serving happens to be a bhakta.
This is because his jeev becomes attached due to that sevã.
Then, just as he thinks about Bhagvãn, he also begins to think about the person who serves his needs.
For that person, this in itself is an obstacle in his worship of Bhagvãn – just as the young deer itself
becomes avidyã (mãyã) for Bharatji.
In this way, a bhakta of Bhagvãn should totally avoid all those who obstruct his worship of Bhagvãn, knowing them to be avidyã.”
19.5 Shreeji Mahãrãj then concluded by adding, “The paramhans and all the sãnkhya-yogi bhaktas should daily say and listen to this talk which I have just delivered.
Specifically, the senior member of a mandal should daily narrate this talk, and others should listen. If the senior person fails to do so, he should do upvãs on that day.
Those who do not come to listen to that talk of Bhagvãn with shraddhã should also do upvãs.
Please remember these words firmly in your lives.”
