Because human life is a combination of matter and spirit soul the whole process of vedic knowledge is directed at liberating the spirit soul from the contamination of matter.
Srimad Bhagavatam 2.1.3,
Our human life is a mixture of spirit soul and matter. It is a holistic process of gaining vedic knowledge. It frees our spirit soul from the polluted matter. It helps us to be liberated. If we learn something with a free mind, we will be able to grasp it. We will be able to understand the true value of the subject matter. Our life will become divine with the gain of vedic knowledge. ISKCON propagates vedic knowledge. We can support the Krishna consciousness movement by promoting the books of Srila Prabhupada. Our life will certainly change if we chant the name of Hare Krishna incessantly. It helps us to remove the impurities. We can understand the connect between the spirit soul and matter. The lifestyle improves with the regular chanting of the holy mantra. Life will change totally. We will be able to understand our divine state. We will be happy to find a pure soul when we chant Hare Krishna maha mantra 16 rounds per day.
The life improves when we follow the vedic system and our mind becomes pure and stress free. We can understand the connection between us and Sri Krishna when we pay respect to Sri Krishna and sing with an open mind and bow down before sri Krishna. Our life becomes enriched. We will be able to build an empire if we are a true devotee of Sri Krisna. People will discover our devotion with the ritual practices and they will love to follow this system and respect it. We will be able to write, sing and speak of Sri Krishna and improve our Krishna Consciousness.
