In our current times, it was the advent of Nichiren Daishonin  who appeared some 220 years in the ten thousand year cycle of the Latter Day of the Law. He offers a method, a practice and a place; a practical means to work towards attaining the sphere of Buddhahood; for all humankind. Nichiren established the sound meditation, chanting of the Infinite Title of the Lotus Sutra, Namu~Myoho~ Renge~ Kyo as a dynamic life force. This profound sound meditation comes from the Eighth World of Realization, enabling all Beings to have a method of conscious communication with the universal Law, touching the Law of Cause, Karma and Effect.
Chanting brings together Object Theory and Subject Reality, with a practical means for all humans to achieve moments of Buddhahood in their present form! Practical proof that mother Earth, is the Buddha’s Pure land.
With Ichinen Sanzen we find the documentary and actual proof that all phenomena are One, there is mutual possession, an inter dependent relationship, contained in every moment of life, in our universe so that fundamentally there is no distinction between the world of Buddhahood and the other nine worlds from Hell to Bodhisattva. This
is an amazing Realization and proof of the Buddha’s earlier quote.
From a practical point of view, most people realize that if you place an unripened green tomato on a sunny windowsill it will quickly ripen and turn red. A ripe tomato and an unripe one are not the same and yet the change takes place within the same fruit. We may be born not yet learning about our Buddha Nature, then when the time is right we are introduced to it and find it appealing and awakening to our desire to find a faith of peaceful means, that brings answers to our quest to give back to the world we were born into; as Buddhists we find that it fits with our open mindedness and inner intuitive knowing finding the light and energy, the Joy of Life.
The lesson is that we humans have free will and choices we can make. We can accept
to live in doubt and suffering, seeing life’s challenges as fate, we can live in the lower worlds of Hell, Hunger, Animality and Anger or we can progress changing our negative karma into positive, enlightened karma, moving through Humanity, Heaven, Bodhisattva and even Buddhahood itself momentarily; thereby attaining a life of indestructible health, happiness, wisdom in our ever changing life cycle of the Ten Worlds.
Attaining Buddhahood can be ours by building on the Four Cornerstones of the wisdom teachings: faith, practice, study and meditation.
I wish you well on your Journey and look forward to hearing about your enlightening moments of Heaven, Realization, Bodhisattva and Buddhahood.
