Our rishis were not just spiritual gurus. They were subjected scientists says Swami Chinmayananda. They concenrated on the upliftment of mankind. Their penance served the humanity. Even modern day scientists do penance but their penance gets ended when they disover or invent a machine or gadgets (they too serve humanity) When you sit for a penance you get focussed in a particular subject rest of the things were forgotten. That means all your energies were channelised towards your goal. This happens to everybody but only thing we don't realize it.
The more one looks inward he/she becomes insular to other things. The ultimate essence of our vedas : THE MAHAVAAKYA: AHAM BRAHMASMI (I am god)SO SIMPLE ISN'T IT but to reach that level the saadhak has to carry out stubborn saadhana no matter how difficult the chosen path was . Have a complete resolute mind. The rest will be taken care by the CREATOR.
OM TAT SAT!
