We are all part of the Universe and have access to the infinite knowledge. But majority remains in the illusion of ignorance. Their faith in their own ignorance is so deep that it is difficult to easily penetrate it. When they come in contact with others whom they think are more knowledgeable, they look up to them and believe blindly.
Even though the ultimate truth is One, the personal truths vary because of the circumstances of life, beliefs and conditionings. For example, vegetarianism is good from many aspects. If you are going to tell an Eskimo that he should follow vegetarianism, how is he going to survive in his place where vegetables are not available?
Even when one is knowledgeable, the truths that he/she speaks are veiled by his/her own beliefs and conditionings. So we have to pass it through our own personal filter, which Nature has endowed us with, before blindly believing or following it.
If your personal filter is not working, you can be in real problem if others’ directions are followed. Once I was told by a supposedly learned man that ladies cannot attain Moksha. When I passed it through my personal filter, I found it to be not true. Then I searched literature and found that he was wrong.
How can one keep the personal filter up to date? By doing meditation daily it is very much possible. Then we can do Reiki self healing or any other spiritual practice. For me, daily puja is also very helpful. There is a misconception that we do puja to appease God. God is Omnipresent, Omnipotent and Omniscient. It is the macrocosm, of which we are the microcosm. The macrocosm doesn’t need the puja from us. But by doing puja and some rituals, we are disciplining and purifying ourselves. Through this we can become aware of our strong connection to the macrocosm!
