Hello Prasanna Shembekar,
To answer both of your queries in a single word, the answer is YES—saying this from personal experience. BUT NOT from the perspective you seem to be understanding it from.
Sherley Johnson has said it right about the interconnection between the different—3—levels [Spiritual Quotient, Emotional Quotient, and Intellectual Quotient] of a human being, in terms of his/her potential to interact with the world-at-large.
To go for a brief recap, during the first half of the last century [1930-1950s], the general focus of the western psychologists was on the IQ—Intellectual Quotient—aspect of a human being. Later, it was discovered that EQ is a better measurement of a person's happiness/satisfaction level. Then came the realization that SQ would be the best and long-term method to cover ALL the aspects of human existence IN ADDITION TO addressing all the shortcomings of the earlier 2 measurement techniques—IQ and EQ.
And the irony of the whole thing was that this was known within India since eons/ages and we depended on the West to rediscover it all over again [like the concept of 'Zero']!!!
Actually, your queries, taken in consonance with your comment about The Bhagavad Gita message ['...where in results are not the focal point of the Karma...'] convey that you are MIXING UP the core principles more than anything else.
Let me explain:
Let's take your Second Query First [Can spirituality quotient help in reducing possibilities of burnout in employees?].
Understanding and enhancing SQ DOESN'T 'per se' reduce Burnout or any such condition DIRECTLY in a person. It only plays a 'critical' role in the 'effect' of such situations/conditions. SQ gives an individual the ABILITY to view situations from DIFFERENT and ALSO MULTIPLE perspectives/angles. This, in turn, enables the person to get a better grasp/understanding of his/her worldly experiences—hate, pain, ecstasy, pressure, etc.—from multiple perspectives, which in turn enables him/her to calibrate his/her 'internal response mechanism'—sort of 'fine-tune' the internal mechanism, which further leads to a better EXTERNAL/OUTWARD response that those around him/her actually see/notice.
To give a very simplistic analogy: when someone shouts/rebukes a group of people, one person may go into a sulk/depression, another may shout back, yet another may complain to the relative power-center [in a work environment, the Boss] and yet another may just ignore the rebuke BUT bear it in mind to hit back later and there COULD be a person who can just smile away the rebuke and forget it and get on with life.
The response mechanism in each of the persons is DIFFERENT...which leads to the 'genetically inherent' SQ [whether the individual notices/knows it or not]. The Original situation was the SAME for all of them, yet the responses were totally different in each of them.
Hope you get the point.
Coming to your Query-1 [can spirituality quotient of a person be improved by some method/practice?].
In general, anything and everything—BOTH positive and negative—can be 'improved/perfected' by practice, and SQ isn't an exception. Like the Saying goes: 'Practice makes a man Perfect'.
Actually, there are multiple methods to improve SQ...some of them being what other members already mentioned: Meditation, Yoga [some of the Asanas]. However, the Best bet would be following the path of 'doing your duty and giving your Best to whatever you are doing'—this is where the "Karma Yogi" concept comes into the scene. In short, it says what I mentioned above—so in such an attitude to life and work, one doesn't need to depend on any Meditation or Yoga to enhance and maintain his/her SQ—which invariably entails additional effort and time—to handle such situations in life.
That doesn't mean a karma yogi doesn't face problems OR isn't focused on the Results—it's just that HIS/HER RESPONSE TO SUCH SITUATIONS IS DIFFERENT, which leads him/her to evolve different and more original solutions to the situations that he/she comes across in the course of work.
Being "not focused on results" DOESN'T MEAN that the 'results' are 'out-of-view'.
If this were so, Krishna wouldn't have said before the War and after he returned from the failed attempt to avert the war—'now that the decision to fight the war has been taken, it's our Dharma to win it'. [There are other angles/aspects to this—of Truth and Dharma—but that would be another topic altogether].
It just means that the person is ALWAYS looking at the LARGER picture—which would ALSO include the possibility of the desired results not being achieved. This MENTALLY prepares him/her for any eventuality. Like that Saying goes: "Strive and Hope for the Best and Prepare for the Worst". And when the person is mentally prepared for ANY and EVERY eventuality, he/she is NOT AFFECTED by what finally happens.
And the whole BEAUTY of this approach is this: More than acting as a 'constraint', such enhanced SQ actually increases the THRESHOLD of the individual to pain/shock/surprises.... AND this leads to the individual to MAINTAIN his/her FOCUS to come out with incredible solutions....in management parlance, "out-of-the-box" thinking [HOW such enhanced thinking capacity is put to use—for positive/good OR negative/bad causes—is a totally different matter altogether]. This is a large subject by itself in Parapsychology Labs now.
From another perspective, WHAT happens IS NOT in YOUR hands [since it is dependent on many variables], but HOW you ALLOW IT TO AFFECT you is absolutely in your hands. That's what SQ attempts to build-up/enhance in an individual.
I hope this hasn't made things more confusing.
Rgds,
