Transcendence


After a quite long time, I read an interesting, thought provoking book. "Transcendence" - My Spiritual Experiences with Pramukh Swamiji by A.P.J. Abdul Kalam with Arun Tiwari. 

This blog has many articles with label "Spiritual Science". This book is also about Spiritual Science. How a renown scientist looks at religion, philosophy, spirituality. I recommend, all people - with scientific temperament - must read:
(1) "Chapter 14. Walking Over the Waves" and 
(2) "Part 3 Fusion of Science and Spirituality", particularly "Chapter 19 Mind Is the Matrix of All Matter" that talks about spirituality, quantum physics etc.

The entire book has diversified interesting topics. It talks about 
- various philosopher, scientists, good people of different time and places. 
- big bang, solar system, universe, galaxy etc. 
- statistics about BAPS, and HDH Pramukh Swami Maharaj. 
- India's space programme
- India's white revolution by Verghese Kurien
- Life of author A.P.J. Abdul Kalam. His native place. His teachers, relatives, other books. Also his role as president of India. 



The last two pages of "chapter 20. Growing into Highly Evolved Physical and Spiritual Being" sheds light on how status quo of our own inner lives harms us: We denounce wisdom of others when it does not fit into our emotional framework. We choose to agree only with opinions of others who share our personal values and feelings...In this state of ignorance, we become subservient, we are at the mercy of the popular status quo.

It also reminds me, a story about bumblebee and an insect. A bumblebee offered ride to an insect across the beautiful garden. The insect took some of the bad smelling matter in his nose with him and could not understand, what the bumblebee was describing about different fragrance of different flowers. The bumblebee realized it and make the insects dawn into pond and take it out, so it can enjoy fragrance. Same way sometimes we are cut of – like a fortress. A Guru open a window in the fortress. Then also we need to put efforts to progress in this spiritual path. I was one of the fortunate persons, who listened to this story directly from HDH Pramukh Swami Maharaj. Prior to that I read it in some book by Swami Vivekanand or Ramkrishna Paramhansa. 

You will like this book, regardless of you are bright atheist or committed religionists. Here is my favorite content from the book. You may also like it. It is in context of Galileo

People who are unable to understand perfectly both scripture and science far outnumber those who do understand them perfectly. The former glancing superficially through the scriptures, could easily arrogate to themselves the authority to decide upon every question of physics on the strength of some word which they have misunderstood, and which was consciously employed by the sacred authors for some different purpose. And the smaller number of understanding men could not dam up the furious torrent of such people. These people would gain the most followers, simply because it is much more pleasant to gain a reputation for wisdom without effort or study, than to consume oneself tirelessly in the most laborious disciplines.

We all have heard famous quote from Shrimad Bhagavad Gita:  


कर्मण्येवाधिकारस्ते मा फलेषु कदाचन ।  

We have control/rights about our own actions only, not on its result / fruit / outcome. The same point when living Guru like HDH Praumkh Swami Maharaj explains with following words, it gives more insight understanding. 

Do not confuse excellence with perfection. Excellence man can reach, but perfection is God's work. 
- Pramukh Swami Maharaj

I have captured many such gems, thought provoking statements in my blog about this book. The book has four sections. So I wrote four blog posts covering pearls of wisdom from each section of the book. You may like to read:

Part 4 Evolution of Creative Leadership


25


Let me not pray to be sheltered from dangers,

but to be fearless in facing them,
Let me not beg for the stilling of my pain, but
for the heart to conquer it. 

Six basic fears in the order of their most common appearance : 

1. fear of poverty
2. fear of criticism
3. fear of ill health
4. fear of loss of someone
5. fear of old age and
6. fear of death. 
- Napoleon Hill (from his classic book 'Think and Grow Rich' 1937)

Man can create nothing which he does not first conceive in the form of an impulse of thought. 

Death is not extinguishing the light; it is only putting out the lamp because the dawn has come. 
- Rabindranath Tagore

May we be fearless, from friends and enemies, from known and unknown. 
From night and day, may all the direction be our allies. 
- From Atharva Veda (XIX, 15:6)

26


Moral excellence was more a matter of divine bequest

- Socrates 

Body has five senses: touch, smell, taste, sight and hearing.
Soul has five qualities: intuition, peace, foresight, trust and empathy. 

Self-giving to God's Will

Is without fail,
A slow-ripening
But most delicious fruit

27


The noble man, he says, will help others even with his bones, whereas the ignoble, governed by fear and greed, is completely worthless, and in a crisis will only sell himself

- Thiruvalluvar - A Tamil poet and philosopher. From book Thirukkural 1080

How could anyone wish to fatten himself by eating fat of other beings? Butchering is disgrace; and eating meat is senseless 

- Thiruvalluvar - A Tamil poet and philosopher. From book Thirukkural 254

Liquor does not differ from poison

- Thiruvalluvar - A Tamil poet and philosopher. From book Thirukkural 926

Ethics, virtues, righteousness and purity indeed make a human different from the beast  


We must be pure. I do not speak merely of the purity of senses. We must observe great purity in our wills, in our intentions - in all our actions. 

- HDH Pramukh Swami Maharaj

The light of love, the purity of grace,

The mind, the Music breathing from (his) face,
The heart whose softness harmonized the whole - 
And, oh! that eye was in itself a Soul !
- Lord Byron (English Poet)

There is more than enough good to go around. There are more than enough create ideas. There is more than enough power, love, joy.

Access to higher consciousness is the purpose of human evolution, and non-violence is the means to access the higher consciousness. 


Eight measures of self realization 

1. Smyak gyan: Appropriate knowledge
2. Smyak darshan: Appropriate philosophy
3. Smyak charitra: Appropriate conduct
Five great vows for appropriate conduct
4. Ahimsa: non-violence
5. Satya: truthfulness
6. Asteya: not stealing
7. Bhramacharya: abstinence
8. Aprigriha: No possessions
- Vardhman Mahaveer (Jainism)

  • English: One world family
  • Sanskrit: Vasudhaiva Kutumbakam
  • Tamil: Every country is my own and all the people are my kinsman. Purananuru Tamil poem in 300-100 BC
  • Unity (tawhid) has 3 categories: Unity of God, Unity of religion and Unity of mankind, in Ahmadiya Muslim community
  • "The earth is one country, and mankind its citizens" - Baha'ullah (founder og Bahai faith) in book "Tablet of Maqsud" 
  • Ubuntu - prominent philosophy of South Africa means 'humanness' 'humanity towards other' ' the belief in a universal bond of sharing that connects all humanity' 
Everything is connected and non-violence is an expression of this interconnection. 

29

As I walked out of the door towards the gate that would lead to my freedom, I know if I didn't leave my bitterness and hatred behind, I'd still be in prison.
- Dr. Nelson Mandela (while coming out prison after 27 years)

Great peacemakers are all people of integrity, of honesty, and of humility. 
- Dr. Nelson Mandela

The weak can never forgive, Forgiveness is the attribute of the strong
- Mahatma Gandhi

Forgiveness is ultimately gift to ourselves. Only through forgiveness can wounds heal. 

The truth is, unless you let go - unless you forgive yourself, unless you forgive the situation, unless you realize that the situation is over - you cannot move forwards

30

The purpose of human life is to serve, and to show compassion and the will to help others.
- Albert Schweitzer

If you are serious about your health, think and take most concern for your peace of mind. 
- Dalai Lama

Compassion has three components
1. cognitive: I understand you
2. affective: I feel for you
3. motivational: I want to help you
- Thupten Jinpa (eminent Tibetan scholar and translator of Dalai Lama)

True renewal relies on three key elements
1. Mindfulness
2. Hope
3. Compassion

i have just three things to teach
1. simplicity
2. patience
3. compassion
These three are your greatest treasures. 
- HDH Pramukh Swami Maharaj

31

Never underestimate the power of dreams and the influence of the human spirit. We are all the same in this motion: the potential for greatness lives within each of us.
- Wilma Rudolph (African-American sprinter)

Vision without action is merely a dream
Action without vision just passes the time;
but vision with action can change the world. 

32

We must reprogramme ourselves to understand that cooperation is a higher principle than competition. 

The senses are not always reliable. Infinite intelligence does not err.

Quite time spent in reflection, a life of rigour and austerity; simple service does at any place to help the poor, the deprived, the disadvantaged and the disabled - and aiding animals and the environment - are method by which infinite intelligence may be most readily contacted. 

Let us make our planet more liveable!

Epilogue

What a dream I had! I thought.
Or is this the dream into which I have not woken?
