And this is not only about having information but also about certain abilities that one get with them. Until something becomes part of our nature which means it is integrated and not part of our ego identity then it is just part of accumulation. And during life we accumulate many things not just information: things, achievements in external reality, even relationships, even experiences. Just to maintain this physical body we accumulate food and the part of its assimilation is not our doing. That is why many can’t control themselves in eating. And all this accumulation is external. It is just having not being. So we can have knowledge and stay ignorant, we can have things and still crave for more the inner feeling of lack is stronger than being satisfied, we can have relationships, fame, fortune but still feel alone and incomplete. All these are signs of ACCUMULATION!
What is cultivation then?
In short it is intériorisation of knowledge, it is assimilate or it is the process from having to being. And in between having and being is doing - doing something with knowledge and that is applying and practicing it. It is contemplation, it is deepening the understanding, it is exploration and experimenting on oneself. Knowledge will give us certain ability, quality and qualifications. But when knowledge is mastered it  means it was a tool of transformation and liberation. 
So cultivation of knowledge has to be a process of change and transformation simply by applying it is not possible to be otherwise. And those who do this, who cultivate knowledge are those who enjoy the journey before reaching the destination. They are those who rather want to be in the presence of God even before realization of God  just remembering about Him and His glory is so powerful that it will lead one to realisation and liberation. And here lies the power of cultivation. 
So having knowledge and learning thanks to knowledge doesn’t necessarily mean the same for everyone. Some are just satisfied with accumulation and their ego empowerment but some are intelligent not just intellectual and they apply the knowledge to achieve mastery and especially in spiritual context to achieve libaration from darkness as ignorance and thanks to cultivation of knowledge and qualities as humblness and gratitude they can enter into Unknown, into mystery. Thanks to cultivation of knowledge one achieved maturity in understanding, one  realised the true knowledge and they are full of trust and hence ready for surrender to the Unknown. 
One point that has to be mentioned is on sangha and satsang as the key places where we receive the fulness of knowledge and much more than that.
In today’s world informations are easily available. Although it makes some things easier it doesn’t mean that this knowledge is necessarily complete and of quality. Even technology that is called as smart no matter how faster can make some things it is not a guarantee for quality and  completeness.
So we can gather so many information and do it so fast and faster but one has to have an alchemical laboratory or a place where information or knowledge will be cultivation and not accumulation. And that laboratory is satsang and sangha. The importance of satsang and sangha lies in the fact that it is the place and space of cultivation and transformation. And only in this laboratory one can receive even that knowledge which cannot be found in books or internet or from AI. 
It means it is not received from the outside but inside in our inner world . And whatever comes from the inside is limitless so one can receive not only knowledge but one can be transformed and liberated.
