Faculty of discrimination, analysis, logical and rational thought: the intellect.
In the yogic understanding, there are 16 dimensions to the human mind. These 16 dimensions fall into four categories. These four categories are known as buddhi, manas, ahankara, and chitta. Buddhi is the intellect – the logical dimension of thought.
▵ Buddhi – The Intellect
Buddhi or the intellect cannot function without a certain bank of memory or data. Depending on the data you have, the intellect plays around. Suppose in your memory system, there are 10 gigabytes of memory. Depending on how sharp your buddhi is, one person can produce, let’s say, a trillion thoughts with these 10 gigabytes. Someone else can produce 10 trillion thoughts with the same 10 gigabytes of memory.In the yogic understanding, there are 16 dimensions to the human mind.If you can think a little better than someone else, it is considered as intelligence today. If someone says one thing and you can say ten things to that, you may be socially smart, but you are not any more intelligent. Unfortunately, in today’s systems of education and academics, everything is determined by this. If you can make more things out of it, you are considered intelligent, which is not true – you only have a sharper buddhi. The buddhi will not take you beyond limits in any way, because it can only function based on the data that is already there. It is not capable of accessing anything beyond that.
