The greatness of Yajna -9-13

1 Gita Sloka every day - Chapter 3 - Karma Yoga - Sloka 10

Has yagna  any place in the cosmic plan?

Sahayagyah prajah srushta purovacha prajapatih I

Anena prasavishyadhvam esha vah astu ishta kama dhruk II sloka 10

सहयज्ञाः प्रजाः सृष्टा पुरोवाच प्रजापतिः।

अनेन प्रसविष्यध्वं एष वः अस्तु इष्ट काम धुक्  ।श्लोक १० 

Having created mankind in the beginning together with yajna, the prajapati said, "By this shall you propagate; this shall be the milch cow of your desires"

The creative force of nature is an aspect of Iswara. Manifesting himself in this aspect He governs and guides human destiny. Then He is known as Prajapati.

Life on earth is wrought with misery, however much a man may pose to be free from it. Still, there is an unfailing way to convert earthly life into a 'mansion of mirth'. When all activities in life are changed to yajna, the spectacle also undergoes a corresponding change. Man is born to give and not to grab. The grabbing man pays the penalty in the form of misery; the giver reaps a reward in the form of undiluted joy. The means to give somehow increases in man who has the mind to give. The resources, the bodily effort and the mental disposition - all these become multiplied in the man of yajna.  His life flowers in being useful to others and fruits in enlightenment.

Kamadhuk is also called Kamadhenu.  It is a mythological milch cow, having a woman's head and a bird's wings. The usefulness of the human the Beast and the Bird are all combined in it. The owner of this divine cow is believed to have all his wants immediately supplied. Allegorically this milch cow is nothing other than yajna. The doer of yajna  is never in want, he is always in affluence. Whatever he wants to offer to others comes to him easily. His bounteous mind is the real kamadhenu.  Because of this frame of mind he is ever in prosperity.  Preyas & Sreyas do both pay homage to him. This is the plan and purpose of the cosmos. 

What is the practical shape that can be given to the spirit of yajna - this is explained in the next sloka
