1) Shreyohi Jnaana Mabhyaasaat: This means knowledge (Jnaana) is better than repeated practice (Abhyaasa). This clearly means that there is no knowledge in repeated practice since both are told as separate entities and also it is told that the second entity is better than the first entity. This clearly proves that the repeated practice is without knowledge. If you say that gold is better than silver, it means gold is not in silver. Hence, repeated practice means the blind traditional practice, which is not analysed properly to see whether such practice is the actual interpretation of the divine scripture or not since analysis was not done in blind practice. 2) Jnanaat Dhyaanam Vishishyate: Meditation (dhyaana) is better than knowledge (Jnaana). The word dhyaana means devotion or firm decision to serve God leaving other worldly bonds. Devotion is generated from knowledge. The word dhyaana means dhee + aana= dhyaana. ‘Dhee’ means intelligence. ‘Aana’ means essence or life of intelligence. Intelligence is the faculty that makes decision through intensive analysis. Such decision is the essence or life of intelligence. Hence, firm decision is dhyaana. 3) Dhyaanaat Karmaphala Tyaagah: Sacrifice of fruit or practical devotion is better than the firm devotion, which is theoretical. This is the action or practice called as karma yoga, which is divided into two sub-parts: a) karma samnyaasa or sacrifice of work, purely meant for saint (Samnyaasi). b) karmaphalatyaaga or sacrifice of fruit of work. 4) Tyaagaat shaanti ranantaram: After sacrifice of the fruit of work, nothing more exists. Shaanti means full stop. Abhyaasa represents the earlier stage before arrival of Shankara in which Purvamemaamsakaas were doing rituals blindly without analysing the Vedic scripture. Then, came Shankara and established knowledge (jnaana) by sharp analysis of the Veda. Then, Ramanuja came establishing devotion (Bhakti) or theoretical firm decision to serve God, which means dhyaana. Finally, Madhva came and stressed that God is the master to be served practically (Sevya) and the soul is practical servant (Sevakaa) indicating practical karma yoga of which sacrifice of fruit of work is very important without any loop holes or cheating. This verse of the Gita indicated the four stages of future time, one after the other since Lord told that He knows past, present and future (Vedaaham...). Lord Krishna told the future trends of spiritual path in the coming Kaliyuga period. Hence, dhyaana does not mean simply closing eyes to concentrate on something, which may be right or wrong. It only means coming to a firm decision that is arrived by the intellectual analysis. The above interpretations are by Shri Datta Swami. His teachings can be found at universal-spirituality.org.
