(ارادھنا)
زندگی بھی، موت بھی تو دیتا ہے
موسموں کے راستے سنوار کر۔۔۔!
ابابیلوں ، بلبلوں اور کبوتروں کو بھیجتا ہے
اے عشق۔۔۔!
پتھروں کو موم کرتے ہوئے بیاباں کو لالہ زار کرنے والے
میں تجھے سبز پتوں پر خط لکھ کر۔۔۔!
لذتِ حقیقت میں ڈوبے چشموں کا۔۔۔،
طواف کرنے والی ہوائوں کے سپرد کروں
تیرے زائروں کی ۔۔۔!
صبح و شام خانقاہی دیواروں کو چومتا پھروں
تو تاثیرِ وصل کی انتہا۔۔۔
تو جوازِ ہجر کا مدعا
خواب کو جھنجھوڑتی ۔۔۔تعبیر کی رگوں میں دوڑتی وفا
اے شافی۔۔۔!
تو ہی بیمار کرتا ہے۔۔۔ تو ہی شفا دیتا ہے
اے خالقِ ارض و سما۔۔۔ اے طبیب ِ کون و مکاں۔۔!
میرا وسیلہ ہے خیر الوریٰ۔۔۔ المد دالمدد۔۔!
یا محصی ، یا محیطُ۔۔۔ المد دالمدد

میں بہلول کی باتیں اطمینان سے سنتا رہا کیونکہ اس کی باتوں میں کہیں کہیں نثری نظم کا اسلوب خوب صورت انداز میں نظر آیا تھا۔ وہ سامنے والے شخص کی فکر آلود سوچ کو معنویت کے ساتھ ، شفق کی تعلق داری میںلے آنے کا ماہر نظر آتا تھا۔ اسی لیے میں نے اپنے قیام کوطویل کرنے کا سوچا ۔ شاید وہ میری سوچ کو پڑھ چکا تھا۔ اسی لیے وہ میرے بولنے سے پہلے بول پڑا۔
اُس نے میری طرف دیکھتے ہوئے کہا۔۔۔خوشبو قید نہیں ہو سکتی۔ شاخیں ہوں گی تو پھول کھل سکے گا۔ بصورتِ دیگر صرف اک بیج ہے جس میں ساری دنیا قید ہے۔ اگر بیج کو سازگار موسم ، زمین ، روشنی اور پانی ملے گا تب ہی وہ روشنی، ہوا کے ساتھ پرندوں کو اپنی طرف بلانے کے قابل ہو گا۔ اسی لیے میں ایک جگہ رہ نہیں سکتا۔ آج ہوائوں کے ساتھ سورج سے باتیں کر رہا ہوں۔۔۔کل نہ جانے کہاں۔۔۔ستاروں کے ساتھ سرگوشیاں کرتے ہوئے، کس حالت میں پڑا...

Teachers Perceptions of Quality and Quality Management Systems at Higher Education Level in Pakistan.

The basic purpose of conducting this study was to explore teachers‟ “perception” of quality and quality management systems at higher education level in Pakistan, by giving a deep focus upon a case of a public sector university of Pakistan „The Karakoram International University Gilgit-Baltistan‟. The basic objectives of the study were to investigate teachers‟ perceived understanding of academic quality a concept, theory and practice in their existing teaching practice at university level and to know, how their perception of quality are being articulated in the university practices by managing quality management systems and formulating the appropriate measures to improve the academic quality in the university. And further to designing a proposed roadmap of quality management system for the university of focus in particular and to all public university of Pakistan in general. The research conducted by using Qualitative Research Method and case study approach of qualitative research design. The purposive sampling techniques were used to identify a sample, and a representative sample was identified relating to the purpose and criteria for the sample of this study from the overall population of the case. Semi-structured interview guide and focused group discussion tools were used mainly to collect the data from the sample of the study. Researchers‟ field notes of observation and written reflections about the everyday experience of field visits were also used as data. The data was transcribed and categorized by creating relevant codes from the repeated expressions of the data. The selected codes were merged into relevant themes to formulate main findings of the study that addressed the objectives. Each theme was then analyzed separately and got the meaning from their expressions and elaborated their perceptions into a discussion and extracted the finding of this study. The study identifies a clear lack of quality meaning and understanding of the concept among the staff. Even though a quality enhancement cell was functioning as matter of obligation from the HEC, but majority of teachers are not even aware of its‟ basic function and significance. The study finds out a huge confusion of quality management with other aspects of teachers‟ professional competencies i.e. Knowing of content information and delivering it to students in the classroom. Majority of the participants of this research were not aware about the basic purpose and the concept of „academic quality management systems‟ in a university to make sure the quality of university teachers‟ performance, as accordance with the certain acceptable standards. Based on the literature review and findings of this study a structure of quality management system is proposed to improve the quality management functions at the public universities in Pakistan.
