The Buddha and the Siddha

There are two Paths. The Lokuttara Path is the path that takes you out of the conditional cosmos altogether. Jainism, Buddhism, and various other traditions were founded upon the Lokuttara Path, even if most of the members of those traditions do not actually aim for transcending the conditional cosmos altogether. Zoroastrianism, Judaism, Christianity, Islam, Sikhism and various other traditions were founded upon the Lokiya Path, the path that aims for the fulfillment of the conditional cosmos, even if some of the members of those traditions may actually aim for the transcendence of the conditional cosmos altogether.

The Lokuttara Path may be called the Path of the Buddha, the Buddha being one who has 'awakened' to the transcendent realm.

The Lokiya Path may be called the Path of the Siddha, the Siddha being one who has 'accomplished' the fulfillment of the conditional realm.

In that sense, Jesus of Nazareth was a Siddha, and Christianity is a Siddhic tradition.

Another name for Siddha is Tantrik.

The Four Boundless States of Mind

The Eighty-Four Mahasiddhas and the Path of Tantra

Attainment of this union in Mahamudra, entails elimination of the barriers between oneself and other people. Suddenly the social field opens up as the siddha empathizes totally with his fellow beings, and since he has attained the powers of mind-reading and prescience (as a direct result of uniting self and other) he is capable of guiding them in their sadhanas. And also, simultaneously with the attainment of the ultimate mystical experience, the siddha is imbued with compassion ("suffering together"), and automatically he acts spontaneously to fulfill the Bodhisattva Vow, which is the commitment to serve others without prejudice in whatever way necessary. Loving kindness, sympathetic joy, compassion and equanimity, the four boundless states of mind, constitute a preparatory meditation that cultivates the feeling of oneness with all beings; the Mahamudra union generates these social virtues, and feelings such as love induce that union. The siddhas of the legends were renowned for their spontaneous effusion of emotion, whether it was for a beautiful woman or a starving puppy, and the songs of the siddhacaryas are full of profound sentiments of love for woman.
