薄伽梵歌 6.5

练习瑜伽（Yoga），约束感官和心意。提升你自己，成为一位瑜伽稳固者（Yogārūḍha）。达到瑜伽境界。作为一位充满活力的瑜伽士，光辉灿烂。不要沉沦于轮回（Saṃsāra）的海洋。不要成为一个世俗之人。不要成为欲望、贪婪和愤怒的奴隶。超越世俗，变得神圣，达到神性。你独自是你的朋友，你独自是你的敌人。所谓的世俗朋友并非你真正的朋友，因为他会执着于你，浪费你的时间，并在你的瑜伽道路上设置障碍。他非常自私，与你保持友谊只是为了从你那里获取某些东西。如果他无法从你那里得到他自私的目的，他就会抛弃你。因此，他实际上是你的敌人。如果你因为妄想或情感而执着于你的朋友，这就会成为你被束缚于轮回（Saṃsāra）的原因。朋友和敌人并非存在于外部，它们只存在于心意之中。是心意将朋友变成敌人，将敌人变成朋友。因此，唯有真我（Ātman）是自我的朋友，唯有真我（Ātman）是自我的敌人。低级心意或不纯净心意（Asuddha Manas）是你真正的敌人，因为它将你束缚于轮回（Saṃsāra）；而高级心意或悦性心意（Suddha Manas，纯净心意）是你真正的朋友，因为它帮助你获得解脱（Moksha）。

Practise Yog. Discipline the senses and the mind. Elevate yourself and become a Yogarudha. Attain to Yoga. Shine gloriously as a dynamic Yogi. Do not sink into the ocean of Samsara (transmigration). Do not become a wordlyminded man. Do not become a slave of lust? greed and anger. Rise above worldliness? become divine and attain Godhead.You alone are your friend you alone are your enemy. The socalled worldly friend is not your real friend? because he gets attached to you? wastes your time and puts obstacles on your path of Yoga. He is very selfish and keeps friendship with you only to extract something. If he is not able to get from you the object of his selfish interest? he forsakes you. Therefore he is your enemy in reality. If you are attached to your friend on account of delusion or affection? this will become a cause of your bondage to Samsara.Friends and enemies are not outside. They exist in the mind only. It is the mind that makes a friend an enemy and an enemy a friend. Therefore the Self alone is the friend of oneself? and the Self alone is the enemy of oneself. The lower mind or the Asuddha Manas (impure mind) is your real enemy because it binds you to the Samsara? and the higher mind or the Sattvic mind (Suddha Manas or the pure mind) is your real friend? because it helps you in the attainment of Moksha.
