The Shri Sutra Kritanga Sutra states that one should abandon sorrow and attachment to the world, becoming "nirapeksha" (free from attachment) to sons, wives, wealth, grain, gold, etc., and strive for liberation (amoksha) by practicing restraint (samyama) in all directions. It is also said:
"Those who are attached to possessions are deceived, but those who are free from attachment cross the ocean of samsara without hindrance. Therefore, one should be free from attachment in all matters." (1)
"Those who are attached to pleasures fall into the terrible ocean of samsara, but those who are free from attachment cross the terrible forest of samsara." (2)
Commentary:
A person who is pure in understanding the nature of samsara, who knows the objects of knowledge (vedya), and who is aware of the nature of things, should abandon the attachment to material possessions, wealth, and family, which are sources of suffering and destruction. They should also abandon the inner torment of ego (mamta) and the karmic inflows of false beliefs (mithyatva), non-restraint (avirati), carelessness (pramada), and passions (kashaya). According to another reading, they should also abandon the inner sorrow (shrota) or grief. Such a person should not even desire sons, wives, wealth, grain, or gold, and should strive for liberation through the practice of restraint until they attain it.
Humans have a strong attachment to their children, so the example of a son is used here. The word "na" (ण) is used here in the sense of a figure of speech.
It is said that those who are attached to possessions are deceived, but those who are free from attachment cross the ocean of samsara without hindrance. Therefore, a person who understands the essence of the teachings (pravachana) should be completely free from attachment.
Those who are attached to pleasures fall into the terrible ocean of samsara, but those who are free from attachment cross the terrible forest of samsara.
Earth, fire, air, grass, trees, seeds, egg-born, womb-born, moisture-born, sweat-born, and sprout-born are all living beings.
Commentary:
A person who has renounced the world (pravrajita) and has a pure mind (suvrata) should strive to practice the vows of non-violence (ahimsa), etc. The verse "Pudhvi u" etc. is meant to explain the concept of non-violence.
Earth-bodied beings (prithvi kayika) are of different types, such as subtle, coarse, large, and small. Fire-bodied, air-bodied, and water-bodied beings are also of different types. Plant-bodied beings (vanaspati kayika) are of many types, such as grass (trina) like kusha, and trees (vriksha) like mango and ashoka, which bear seeds (beeja). Seeds include rice, wheat, and barley. These are all one-sensed beings (ekendriya).
Egg-born (motaja) beings include elephants, rhinoceroses, etc. Womb-born (jarayuja) beings include cows, humans, etc. Moisture-born (rasaja) beings are born from milk, butter, etc. Sweat-born (sansweda ja) beings include flies, mosquitoes, etc. Sprout-born (udbhija) beings include creepers, etc.
Since beings of unknown types are difficult to protect from harm, they are described in detail here.
