For a person who knows little of Buddhism, I can say it is basically a collection of terms which have definitions. Because someone may be new this kind of language, it seems as though they don't know anything about it, but they probably do understand a lot in their own language, and even more in their own personal way of expressing.
The first definition is: "Buddha" means the enlightenment in yourself, and we recognise each other as that. This is why we appreciate so much each others' presence. You are like me in terms of the enlightened spirit. This leads to loving kindness - of which no explanation is required.
The dedication of Guatama's (Buddha's) life was to recognise there is suffering, discover the primal cause of suffering, and through that understanding, bring an end to suffering. That's the purpose of Buddhism, which pertains to any person's life (A comprehensive discourse on "Four Noble Truths" here:

Even though Buddhism has become a religion with numerous sects, it is better to remove religiosity from it. The teachings of Guatama the Buddha are accessible to anyone. If you are of another religion or culture, continue as such, for this is not a conversion exercise.
If you are here, Buddha is here as the enlightenment yourself. The spiritual 'beingness' is present with, and present as, you, me, us.
The word 'practice' is daunting isn't it? It sounds like someone will give you instructions which you then ardently follow. It can be that, but in the context of a forum discussion, the practice is to be self aware, considerate of others, and expressing one's self from that heart of loving kindness. Is that heart not the natural expression of your most enlightened self?
